Do You Share Ancient Irish DNA? Find Out With GEDmatch

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 NUMBERDESCRIPTION
F999805Ballynahatty Neolithic Female
F999800Rathlin Bronze Age Male 1
F999802Rathlin Bronze Age Male 2
F999801Rathlin 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

Upload Your DNA to GEDmatch

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

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.

    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).

  15. I have a strong maternal Irish connection from Mayo. Dublin Tipperary and Longford. The results of the comparison is as follows:

  16. 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).

  22. 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:

    • 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.

  27. 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!

  28. 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.

  31. I share a total of 15.6cM over 4 chromosomes with Ballynahatty woman, and 14.8 cM over 4 chromosomes with Rathlin1. No matches on the other two.
    The largest segment shared with Ballynahatty woman is 5.5cM on Chr1.
    Migration patterns fascinate me. I am predominantly English with no known Irish ancestry at all, though I do have one grandparent from Lithuania. My English grandfather thought his surname was of Viking origin.

  33. 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

  37. 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.

  38. 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?

    Reply
    • 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.
