Do you share DNA with any of the four ancient Irish samples on GEDmatch? You can compare your DNA to Neolithic and Bronze Age remains uncovered in Northern Ireland. Here’s how to go about it.
How To Research Ancient Irish DNA Samples on GEDmatch
We have another article on using GEDmatch to research Neanderthal and other Archaic DNA samples. GEDmatch has a dedicated tool called “Archaic DNA Matches” to compare your DNA against a collection of specific samples.
However, the ancient Irish samples are not part of the Archaic DNA collection.
The Irish samples were pepared by Matt Kitching using the same techniques and uploaded as individual DNA kits to GEDmatch.
So, you will use the standard one-to-one comparison tool on GEDmatch to compare your DNA with each kit. There is a step-by-step tutorial in this article that takes you through the process. And we have a video walkthrough.
If you already know how to use GEDmatch tools, then here are the kit numbers:
| KIT NUMBER | DESCRIPTION |
| F999805 | Ballynahatty Neolithic Female |
| F999800 | Rathlin Bronze Age Male 1 |
| F999802 | Rathlin Bronze Age Male 2 |
| F999801 | Rathlin Bronze Age Male 3 |
The Ballynahatty Neolithic Female
The oldest sample is a Neolithic female found in the townland of Ballynahatty, on the southern side of Belfast, Northern Ireland. The remains are dated to about 5,200 years old.
I’ve pinned the location in this map to show where we’re talking about.
Researchers say that this woman had brown eyes and black hair. When comparing her genetic makeup to modern humans, she is most akin to people of Spain and Sardinia. But her DNA also points to ancestors from the Middle East.
There’s a photo of a reconstruction of the woman’s head in this article from the BBC.
The Rathlin Island Bronze Age Males
Rathlin Island is further north, off the coast of Antrim, Northern Ireland. People still live there, which makes it the most northern inhabited island off the coast of the island of Ireland.
These three male specimens date back to the Bronze age. They are dated from three to four thousand years old.
Unlike the Ballynahatty female, these men had genetic variants for blue eyes. They also have the most common Y type found in the modern Irish population. The DNA point to ancestors from the Pontic Steppes.
Evidence for Mass Migration Into Ireland
Dr Lara Cassidy of Trinity College Dublin says that modern Celts are closer to the Rathlin Island men than the Ballynahatty woman.
Genetic affinity is strongest between the Bronze Age genomes and modern Irish, Scottish and Welsh.
Professor Dan Bradley of Trinity points out that these genomes show evidence of a wave of migration into the island of Ireland.
There was a great wave of genome change that swept into Europe from above the Black Sea into Bronze Age Europe and we now know it washed all the way to the shores of its most westerly island.
Just in case you’re puzzled by Professor Bradley’s Irish fondness for verbal flair – the “most westerly island of Europe” is, indeed, Ireland.
Ready To Compare Your DNA To These Ancient Irish?
Now that you have a bit of background, here is how to compare your own DNA to these four samples. You will need to have tested with one of the main consumer DNA testing companies. These include:
- Ancestry
- 23andMe
- MyHeritage
- FamilyTreeDNA
- Living DNA

A Video Walkthrough Of Comparing DNA With Ancient Irish Matches
If you prefer video, then here you go. Read further for an illustrated guide.
A Step-By-Step Guide To Comparing Your DNA To Ancient Irish Matches
1. Launch The One-To-One Autosomal Comparison Report
2. Enter Your Kit Number And One Of the Ancient Samples
If you’re not sure, this article section shows you how to find your own GEDmatch kit number.
3. Set The Minimum Threshold To 3 cM
If you don’t set a threshold, the default 7 cM will be used. You will probably not get any shared DNA at that level.
4. Compare Your DNA!
Hit the Compare button and scroll down the display to find any shared DNA.
How Do You Compare With Me?
I share 3.3 cM with the Ballynahatty female on chromosome #15.
I share 4.8 cM with Rathlin Man 1 on chromosome #18.
There is no shared DNA above 3 cM between myself and the other two Rathlin Island specimens.
Feel free to post a comment below with your own results.
Be Cautious With Small Segments Of DNA
It’s important not to draw conclusions or make too much out of such small segments of DNA. At these low levels, the reason for matching segments could be due to chance.
Our article on matching archaic DNA matches has a section on low thresholds of shared DNA. I discuss inheritance by chance, by common ancestor, and by population. It’s worth a read if you’re not familiar with these terms.
I’ll repeat here that examining these ancient DNA samples is for pure curiosity and fascination. I simply marvel at the fact that I can compare DNA to people born on the same island as me – thousands of years ago.

Running the Ancient data tool I show at 0.5, 1 and 2cm connection with some/all 4 but it has all but disappeared with only Rathlin1 remaining at 2cm then gone by 3cm. This means that when I run the one to one I get no match at all. Disappointing somewhat but reassuring that these are my strongest (greatest matches) on all the Archaic data groups.

My mother is mainly Irish/English, where as I have a chunk of Sicilian/Chilean ( originally from Spain)
But what is truly mind-blowing is your link mentioned that one of the Bronze Males carried the mutation for Haemochromatosis (Iron overload) and the Ballynahatty woman also carried a variant for H associated with increased risk. I actually have that increased risk variation which is aggressive. My mother is a carrier.
Thank you for the details.
The haemochromatosis gene is more prevalent with Irish heritage, one in five modern Irish are carriers.

Weird, buy maybe relevant that my mum’s matches are on 2 Chromosomes.
The description fits her to a tee – black hair, brown eyes, regularly mistaken for Mediterranean origin when she was young.
Her dad was (recently discovered), almost 75% Irish – records patchy – Taylors from Antrim, Johnston’s, Kings from same and Belfast area. I have DNA evidence of ancestors that went to the US – to a Samuel Taylor (1700).

Thank you, that’s very interesting about your mum.
Just to add – the area I have for my maternal Grandfathers Antrim Taylor’s is Ahoghill? Others link to Belfast and Dromore.
Ahoghill is in the same county, Antrim, but further north than Ballynahatty. Getting closer to Rathlin Island, actually 🙂
I have a 8.2cm match with Rathlin Male 1on Chromosome 1 and smaller matches on 3 other chromosomes. I have smaller matches, largest 3.6 cm, with Ballynatty female on 4 chromosomes. My mother’s Irish ancestry is from Ulster.
My only match is with Rathlin male 1: 3.1 cM on Chr #6 and 6.6 cM on Chr #9

Rathin Man 1
Chromosome 14 3.4cM
Chromosome 15 3.5 cM
Chromosome 18 5.1 cM
Chromosome 22 4.8 cM
I see that there a quite a few of us who share chromosome 18 under Rathin Man 1
No matches for Rathin Man 2 or 3
Yes, Rathlin Man 1 is standing out.
Very interesting. Is it true that the Rathlin 1 man has most connection with the modern population of Ireland?
I share 44.8 cms with him over 10 chromosomes (11 segs): largest segment 6.6.
This is mostly on my mothers side but I must have some from my (Cornish plus 1/4 Irish) father’s side also – as my mother’s match to Rathlin 1 is slightly less than me at 33.9 cms.
My paternal haplogroup also matches the Longniddry L1066 ancient DNA sample (East Lothian Scotland).
Dominic, you raise a good question about whether Rathlin 1 has the most affinity with modern Irish. I’ll have to dig into this a bit more.
I had an ancestor that immigrated to the US from Nothern Ireland to the US in the 1700’s.
I share matches with Rathlin1 and the female.

What does it mean to have a match so high (relatively speaking) on the one segment? Any insight?
No, I wasn’t expecting anyone to get that high. I’m going to ask a few people I know to see if its a major outlier. I’ve got your email (because of your comment) so if I find anything interesting, I’ll send you the info.

I am an American mongrel, A657252. Both of my mother’s parents were adopted, so we never knew much about her family, but we did know that red hair has come up a few times in her family, including my son, plus my own beard is red (while the rest of my hair is brown), so we always figured we had some Irish or Scottish heritage. Based on recent ancestry research using my grandmother’s birth certificate, I have been able to confirm both Irish & Scottish, many many generations back in the deep hills of Kentucky.
Now with this ancient Irish DNA, I see the strongest connection with Rathlin Bronze Age Male 1:

That was fun! Woman and Guy 1. Paternal family is from Achill Island, maternal family from the north but Scots Irish.
Thanks!
Guy 1 is outdoing the other two males for sure!
I’m a 25.7 cM match with Rathlin Bronze Age Male 1. Is that significant? Largest segment is 5.7 cM.
The individual segments are more indicative than summing them up. But 5.7 cm is a higher segment size than I have with any of the specimens.

Paternal family: Clonakilty, other Cork and Glensaul (Partry). Red hair and grey eyes, very commonly featuring. Maternal family: Dublin and Wexford. All with very dark hair and hard to tell in old photos but likely brown eyes. My maternal great great grandmother from Dublin, was described as having the appearance of being Spanish.
thank you for the background, very interesting.
I share 3.1 cM on chromosome 6 with the Ballynahatty woman. I have multiple Irish heritage lines, from Antrim, Galway, Dublin and Wicklow. No matches to the men. Fascinating!
I have Irish/Scottish/Welsh/Scandinavian/East European/Middle Eastern. My father is Irish/Scottish/Scandinavian/Baltic.
My father’s mother and her brother were very dark skinned, Black hair, but my Grandmother had very Blue eyes!… and the rest of the siblings and their parents had Sandy fair hair and fair skin. Another who inherited the very dark skin and hair was the only child and daughter of my Grandmother’s brother who also had the same colouration. My Grandmother’s family immigrated in the late 1800’s from Ireland. My father’s Paternal Scottish side also had dark skin and hair however NOT as dark as his Irish mother, Uncle and this Uncle’s daughter.
The Mystery of where the Dark skin and Hair of my Grandmother, her brother and his daughter ‘is still a Mystery. She used to get asked if she was West Indian or Maori.

Thank you for laying it out!
This is quite interesting! I have run 3 kits and none have matches to the 2nd or 3rd males.
The first kit, my mother-in-law, whose grandparents were from Antrim, has 9 shared segments with the Ballynahatty female, the largest being 4.1 cM.
Her son has 5 shared segments, the largest being 8 cM. (He does have Irish ancestors on his father’s side.)
I have 3 matches to the female, the largest being 3.8 cM. 1/2 of my immediate ancestors are from southern Ireland.
Our matches with the first male:
m-i-l 7 shared segs, largest being 4.7 cM
son 5 shared segs, largest being 5.1 cM
me 5 shared segs, largest being 5.5 cM

I hope that someone realizes that F999800 has DNA from the c15 region 27-30M that is excess IBD per “Relationship Estimation from Whole-Genome Sequence Data” by Ling et al (2014) https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1004144 (Table 3 “Genomic Regions in hg19 coordinates of at least 5-to-expected IBD of at least 4-fold”).
I find this very interesting that such an ancient kit has this excess IBD region. I hope someone will follow up with research on that and see if they can make some sense out of it — or determine if it is just a fluke of so many generations of genetic recombinations.
Great point.
I share a total of 11.9 cM over 3 segments with F999805, the Ballynhatty Neolithic female – the largest segment being 5.3 cM, chromosome 10
With F999800, the Rathlin Bronze Age male 1, I share a total of 36.9 cM – the largest segment being 6.2 cM, chromosome 15
With Rathlin Bronze Age male 2, it’s a share of only 3.5 cM, chromosome 13
And I share none with Rathlin Bronze Age male 3.
Interesting – but does it meaning anything?
Does it mean anything? Good question.
With current technology – with these low segments, all we can say for sure is that we’re all human! The lower the segment size, the higher the possibility that this is Identity By Chance. Genealogically, we are usually looking for a common ancestor with our DNA matches and that’s something that we cannot determine i.e. Identity By Descent.
The other possibility is that its Identity By Population i.e. the common DNA is prevalent in a particular community or region and has passed down to modern times. Right now, we can’t determine between these three possibilities. That may change with future technology and analysis.
Fascinating stuff!

I’d like to figure out my maternal Line. My brick wall is Margaret O’connor. She moved from Ireland to Canada. Her husband was John Dunn. He wasn’t the only John Dunn to say the least lol. We all ended up in Upstate NY shortly there after. They were protestants. A lot of DNA matches have he listed as Mary Connor. My maternal haplogoup is U5b2c2b

This looks like some actual possibilitities. Though individual matches are quite small, there are a lot of them. MyHeritage claims 27% Irish, Scottish, and Welsh. No one else puts it that high; Ancestry thinks 10% Welsh, 6% Irish; 23andMe says total 15.9% all Celtic AND British. Looking at actual paper-trail locations, a big part of the Welsh is from Anglesey, near Holyhead, just across the water from Ireland. Most of my DNA is not from the UK.

Edit to say “Most of the rest of my DNA is not from the UK or Ireland” just to clarify that that is what I meant.
Thank you for the details!
I find this whole field fascinating – but despite the tidal wave of archaeological DNA being documented now, it’s just not getting through to places like GedMatch where the average person can compare. Felix’s amazing effort pioneered this, but he stopped. Matt picked up with the Irish results, but he hasn’t blogged since 2016.
The really old DNA will be in frustratingly short sequences, but, for example, sequences from London plague-pits might stand a good chance at being in genealogically useful lengths.
I tried dipping my toes in this stuff a year or so ago, but got overwhelmed quickly with the terminology (file conversion stuff). It seems like it ought to be relatively straight-forward – if someone laid out the process. Are you someone who could blog this? Or are there reasons why, perhaps GedMatch would prefer it didn’t happen? Cheers, Mike
I did tinker with the tools that are still on Felix website, but this isn’t my wheelhouse either.
I assume Verogen (the company who bought Gedmatch) are neutral about it or they’d take down the Archaic Ancestors link. Much of the website is a collection of research projects and sometimes the researchers move on (taking their documentation with them).
Thanks Margaret, if the stars align I might have another crack at it! Cheers.
I don’t understand how, with one odd exception, not a single one of my matches with this Irish DNA match in any way with the matches of my mother, father, father’s sister, father’s cousin and mother’s cousin have. How does this work?
That one exception is with F999800 Rathlin Bronze Age Male 1
My one fragment in common with my father’s (phased) DNA both end at the same point.
Me: Chr 1 11,797,186-13,176,463 3.6 cM 302 SNPs
Father: Chr 1 11,922,298-13,176,463 3.2 cM 231 SNPs
So my match is longer than my father’s, and my matches on two other chromosomes are not in either my mother or father.
I see other people are getting similar results.
Cheers,
Mike
I answered this question on my blog recently Mike, see https://blackravengenealogy.blogspot.com/2020/11/ancient-irish-dna-or-lack-of.html
Good article, Dara!
Oh good- thanks Dara! I’ll need some time to read and digest your post properly – but much appreciate you pointing it out. Cheers, Mike
So basically no mystery – the fact that my ‘shared’ ancient DNA is found neither in my mother’s or my father’s genome, is the proof that its pure coincidence. As you say, “truly false matches”. Oh well… ):
Thanks, Mike and Dara. Like many, I’m not in a position to have my parents’ DNA. So it’s very useful to see the results from a wider net.

Do we know who these old people are? Would be nice to trace the line of descendents from them. I have an over 7cm with the female. I match with the female at 7.5 cm on Chr 22. There are several others too. I also have a match with the first two males.
Thanks for posting the details. We don’t have lines for them.
I have no Irish ancestry as far back as my paper trail goes (i.e. roughly mid 18th century) but one half of my family is from south and central Wales, so I would expect there to be some similarity and indeed there is.
I share 24.8 cM with Rathlin Bronze Age Male 1, with the largest segment being 5.7 cM:
Chr 3: 3.4 + 3
Chr 11: 3.7
Chr 15 5.7
Chr 18: 5.5
Chr 20 3.5
I also have a smaller match with the Ballynahatty female (Chr 16: 3.3 cM) and nothing at all with the other two.
thank you for the details.
Thank you for having posted the instructions for comparing! It would be really interesting to read more if future research shows how much DNA from these people is shared by the modern population, not only in Ireland but in the UK, and if it is more commonly shared by people from the Celtic areas of west and north Britain than from the east.
My Dad has 6.1 on Chrom. 4 and 5.7 on Chrom. 18. I have 5.7 and 5.3 at same spots. On 4 our match begins at exactly the same spot, on 18 it ends at exactly the same spot. Is this significant?
Once the size is below 7 cM you’re dealing with a high possibility of chance. But that your dad has similar positions is interesting.
I am an American – so I am a mutt….
But this is my results, which I did find fascinating.
Ballynahatty Chromosome 23 Total Segment 16.7 Cm Largest Segment 6.1
Rathlin1 Total 16.4CM Largest segment = 3.6 cm
(Chr 1 3.1CM, Chr 2 3.2CM, Chr 4 3.3CM, Chr 10 3.4CM, Chr 18 3.6CM)
Rathlin2 None
Rathlin3 None
Interestingly, my first cousin results for Ballynathatty was Chromosome 23
Total segments 16.9cM Largest segment = 5.2 cM 4 shared segments
And 3 of them overlapped with my segments almost exactly.
but she had none for Rathlin 1, 2, or 3
Thank you for the breakdown

Bonjour,
je m’appelle Richard et f’ai fait le test:
je partage le chromosome11: 3.2cM et chromosome13: 3.8CM
ce qui me surprend c’est que ma famille est d’Afrique du Nord depuis des siècles et ce qui est très surprenant c’est que sur My heritage j’ai des correspondances avec des anglo-saxons!?
Merci. Les nombres sont petit. C’est peut-etre un question du chance: heritage aleatoire.
Sorry, my French is poor – what I’m saying is that there is always the possibility of chance involved with small centimorgans, due to the random nature of inheritance.

Hi Margaret,
Thank you for enabling us to compare our DNA with these ancient ancestors, it is absolutely fascinating. My results are as follows:
Ballynahatty Neolithic Female, F999805.
She and I share three segments:
Chr 2: 3.5 cM
Chr 7: 3.2 cM
Chr 12: 3.1cM
Rathlin Bronze Age Male 1 – F999800
He and I share eight segments.
Chr 1, there are two segments: 8.6 cM and 4.7cM
Chr 8: 3.1 cM
Chr 8: 4cM
Chr 10: 3.5cM
Chr 13; 4 cM
Chr 18: 5.4cM
Chr 19: 3.3cM
Rathlin Bronze Age Male 2 – F999802
He and I have no shared segments.
Rathlin Bronze Age Male 3 – F999801
He and I have no shared segments.
Margaret, in your video you mentioned that your maternal line comes from Cavan. My maternal line paper trail takes me back to Cavan in the late 1700s. I love it when DNA shows the accuracy of previous work.
thanks for posting the details.
That’s impressive that you can get back to the late 1700s, I can get there for some lines but not all. That’s about the edge of the records.
Hello,
From the Netherlands two small segments.
Ballynahatty woman: Chr. 10, 3.1 cM, 206 SNP’s;
Rathlin male no. 1: Chr. 1, 4.3 cM, 254 SNP’s.
Nothing on the other males.
Probably noise but fun to see. WGS is on the way so maybe more surprises will be revealed once it is there…..
Greetings.

Well I’m still a little bit confused how I could be related to this very ancient human from Irish while I’m not even an European. I’m a native of north Borneo in southeast Asia. I just uploaded my DNA file to GED match just to find out more about the origin of my people when i stumble upon this information. I’m also had a 4 percent Baltic DNA, and another 4.9 percent from east Meditrerranean
If you have low cm matches, then this can be due to chance nature of inheritance. Also, many modern Irish people will have low connections to thes ancient samples. We are looking at periods of migration of peoples across continents.
If you’re interested in more recent times (e.g. within ten generations), then this won’t be much use to you. You wan want to start playing with the gedmatch admixture calculators – but remember they are also focused on ancient eras (neolithic etc).
For more recent ethnicity research, you’re better off with the estimates given by your DNA test provider (Ancestry? MyHeritage?). But you might have the same problem as I do with my half-African heritage – none of the DNA sites are currently great for non-European heritage.
Hello,
Just discovered GEDmatch and have discovered a lot which I am finding very fascinating.
Closest matches were:
Rathlin1 @ 4 segments with the largest at 6.1 cM. Total half match segments 18.3 cM. Ballynahatty @ 4 segments with the largest at 4.5 cM. Total half match segments 14.2 cM. No shared segments with the other 2 males.
This is intriguing because my DNA is Portuguese and Spanish dominate. This is the juice I have been searching for.
thank you for the details. And good luck with your searching!
I share 1 segment with Ballynahatty – Chr. 12 = 3cM
I share 10 segments with Rathlin man 1;
Chr. 1 = 3.3cM, Chr. 2 = 3.7cM, Chr. 4(x2) = 3.3cM and 3.7cM, Chr. 13 = 3.3cM, Chr. 14(x2) = 4.1cM and 3.2cM, Chr. 15 = 4cM, Chr. 18 = 3.2cM, Chr. 21 = 3.1
I don’t share any dna with Rathlin man 2 or 3
I am from Scotland. I am 27.1% Scottish/Irish/Welsh, 5.2% Balkan and 3.1% Ashkenazi Jewish
thank you for the details.
Strangely enough I have no known Irish ancestors. I am Spanish Basque and Portuguese with documented ancestors back to mid 1600. I have brown hair and hazel eyes. I have huge numbers of Neolithic and WHG in my lines. I have 2 small segs on chr 21, 6 for a total 7.2cM for F999805 Ballynahatty Neolithic Female.

You are most welcome. Is an 8+ cM segment unusual for such an ancient match?
Yes, its one of the highest reported here. Most people are seeing 3-4 cm. At 8 cM, you’re still well within the range of inheritance by chance but less so than the lower numbers.

I have Irish ancestors maternal and paternal from central Ireland – Cork, Limerick, and Tipperary. When I used the GEDMATCH ancient ancestors tool, the Rathlin 1 and Balynahatty showed the most small matches at .5, compared to any other ancient DNA. I have several segments over 5 cm in common with Rathlin 1, and a couple over 2 cm with Balynahatty. At one point a DNA site showed me having Sardinian ancestors (which I do not), but given that Balynahatty is similar to current Sardinian and Spanish populations, I now see where that signal came from. I carry a copy of the hemochromatosis gene.
Hi, our four grandparents were all from Ireland.
One line was from Dreenan, Co. Derry, Northern Ireland.
My 2 sisters and I have Gedmatch kits. We are very different in our appearance. I have medium brown hair, fair skin and dark blue eyes. One sister (sister 1) has very pale blue eyes, blonde curly hair and good complexion. My other sister (sister 2) looks quite Spanish, she has hazel eyes, dark brown hair and olive skin.
We have Co. Galway, Co. Limerick, Co. Tipperary and Co. Clare and possibly Co. Cork heritage as well.
