Welsh Names Celebrate St David’s Day

Welsh Names Celebrate St David’s Day

Dydd Gŵyl Dewi hapus, and a happy St David’s Day to you too! Let’s celebrate the national festival of Wales with a fresh look at Welsh names.

Welsh baby names are a treasure hoard that sometimes gets overshadowed by the Irish and Scottish cousins. You definitely know a few — Megan, Dylan, Owen, Arthur — but beyond that, there are so many more that are barely known outside Wales and the UK, but really should be.

Here’s our guide to the best Welsh names for every style. We’ve erred towards more anglo-friendly spellings and pronunciations so they’ll sound great whether you’re in Cardiff or Chicago. (But if names like Lleucu and Wmffre make your heart sing, then all power to you!)

Popular Welsh names: Wales versus the USA

Most of the best-known Welsh names in the States follow the “two syllables ending in N” template that Welsh does very well: Owen, Dylan, Evan, Gavin, Tristan, Griffin, Megan, Morgan.

Other internationally popular Welsh names come from history and legend, like Arthur, Rhys, Idris, and Gwendolyn, and from patronymic surnames, like Maddox, Bowen and Davis. Gender-swapping Meredith is a softer option. Kai counts Welsh among its many international roots: he’s Sir Kay of the Round Table (although in Wales today the more common spelling is Cai).

Welsh names are more popular for American boys than for girls: Owen was number 21 in 2019, but you have to go way down to number 156 to find a girl name with Welsh roots (that’s Reese).

In Wales, the very top names are much the same as the rest of the UK: Oliver and Noah, Olivia and Amelia (plus many more in the charts) . But look down the list and you’ll soon find plenty of names with a more local flavor.

In Wales’s Top 100 in 2019 (data from the Office of National Statistics) there are traditional names with deep Welsh roots that have been used for hundreds of years, like Gruffydd and Gwen. There are some that have been revived or invented in modern times, such as legendary Osian and nature name Ffion, and cymricized spellings of popular English names, like Hari and Alys. From the Top 100:

    Like your names short and sweet?
