The trendy name Croía (pronounced KREE-a) rose from 95th in 2020, to 52nd in 2021, to 38th in 2022, to 24th in 2023, to 16th last year. Do you think it will reach the top 10 in 2025?

Speaking of names on the upswing, the fastest-rising girl names in the top 100 were Maya (in terms of number of babies) and Rhea (in terms of rank). Likewise, the fastest-rising boy names in the top 100 were Rían (in terms of number of babies) and Caleb (in terms of rank).

And what about the names at the other end of the spectrum? Here’s a selection of the names given to just 3 babies each in Ireland last year:

Baby names with OO: Cooper, Brooklyn, Rooney

Looking for baby names that feature the letter-pair OO?

I’ve collected oodles of OO names for you in this post!

Before we get to the names, though, let’s get one big question out of the way…

What sound does OO make?

In today’s English, OO commonly makes the sound you hear in the words boot, food, and moon. But it can also make other sounds, such as the ones you hear in the words blood, or door, or good.

Why all this diversity?

A lot of it has to do with the Great Vowel Shift, which lasted from the late 14th century until about 1700. The GVS was a major factor in the transition from Middle English to Modern English.

In Middle English, OO tended to make a “long o” sound. (As one of my sources explained, “scribes often indicated a long vowel sound by doubling the vowel letter.”) So, in Middle English, the words boot, food, and moon sounded more like “boat,” “foad,” and “moan.”

During the Great Vowel Shift, the pronunciation of most long vowel sounds inexplicably shifted “upward” in the mouth, and the words boot, food, and moon acquired their present-day pronunciations.

But it’s not quite as simple as that. Because some words underwent multiple pronunciation changes during the GVS, while others didn’t undergo any change at all.

And this resulted in OO having a variety of pronunciations in Modern English.

Now, back to the names!

Speaking of surnames (and surnames being used as first names), did you know that five U.S. presidents had OO-names? Weirdly, all five served during the first half of the 20th century:

  • Theodore Roosevelt (in office from 1901 to 1909)
  • Woodrow Wilson (1913 to 1921)
  • Calvin Coolidge (1923 to 1929)
  • Herbert Hoover (1929 to 1933)
  • Franklin D. Roosevelt (1933 to 1945)

Which of all the OO names above to do you like most? (Can you think of any that I missed?) Let me know in the comments!
