50 Gaelic Baby Names: Meanings & Origins

If you’ve ever been a bit confused about the difference between Irish, Scottish, Gaelic, and Celtic, you’re not alone. If you were to look at a tree diagram, you’d see Celtic at the top with two families underneath: Brythonig and Goidelic.

The latter is where you'll find a trio of three primary languages: Irish Gaelic, Scottish Gaelic, and Manx.

While both Scottish and Irish Gaelic languages technically come from the same lineage, each has their own dialect and vocabulary.

Below we’ve rounded up 50 Gaelic boys and girls names that come from both.
