Short Last Names Beginning With O

This article is about short last names beginning with O that are under five letters.

We look at the most common four-letter, three-letter, and two-letter O surnames in America in recent years.

We also investigate whether anybody in the United States is named simply “O”. There are probably more than you think!

Using The 2010 U.S. Census

We used the 2010 U.S. Census to look at the numbers for these names.

That allowed us to grab the top ten in each category of four, three, and two-letter names.

The 2010 census also gives a breakdown of how people reported their ethnicity. Some of these names have at least tiny percentages of all the possible ethnic categories.

We’ve included the top two ethnicities in the tables below when the second is above 20%. The first listed ethnicity has the higher percentage.

The name Ott is of Germanic origin. It has a similar meaning to the name Otto, which we covered in the previous section.

Two Letter Last Names Starting With O

I’ve covered the other letters in the alphabet in a series of articles and I usually can’t give the top ten two-letter names.

That’s because there are usually less than ten in the 2010 U.S. census.

Two-letter surnames starting with O are the big exception. They are generally more numerous. Here is the top ten.

About 95% declared as Asian or Pacific Islander in the census. The name Oh can have Chinese, Japanese, or Korean origins.

Most of the top names here are predominantly Asian or Pacific Islander.

The exception is the surname Oz, which was reported at 88% of white respondents.

Oz has several origins depending on the region. It can be of Jewish origin with the meaning coming from the Hebrew word for strength.

It can also be of Turkish origin.

O As A One-Letter Last Name

Statistics for the name “O” aren’t in the published U.S. census of 2010. That means that even if it exists in the country, there weren’t one hundred people with the name.

Could there be a few families with “O” as their name in the United States?

The late mathematician A. Ross Eckler conducted a study of one-letter names in the 1970s using telephone directories.

You may be too young to remember telephone directories stacked on the hall table. Here’s a picture:

Eckler pointed out that many examples in the books were errors that came from reversing initials and last names.

However, he was satisfied that the letter “O” was an exception.

Eckler noted that the name was relatively common in Korea. Therefore, we should expect it to appear in the United States from immigration.

He found fifty-two entries under the single-letter name “O” in a review of directories from 1972 to 1981.

Here are some examples:

  • Taekun O
  • Kumsok O
  • Jong Sok O
  • Ook Whon O
  • Thomas O jr.

Let’s take a closer at the last example of “Thomas O jr.”. Could this be a typographic error for someone with an initial O?

For example, could the correct name be “O Thomas jr.”?

Probably. However, when the names appear to be of Korean origin, some are surely correct.
