From the experts:

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.

One of the name's most famous bearers is the 1995 Nobel Prize-winning Irish poet Seamus Heaney. Seamus is also a Harry Potter name—Seamus Finnigan is a half-blood wizard friend of Harry's.

At a time when the police force was predominantly Irish, "shamus" became a slang term for a detective.

Cool nickname of Sea or Shai..

Ruanne Says:


Maybe you could use an alternate spelling. I was thinking Sheamus, which gets you pretty close. Surprised Nameberry doesn't list it.

Love the name, on the one hand. But it also sounds like "shame us."

Mrspen Says:


I love the pronunciation of the name... but I don't know many who would say it the right way. I get that it's traditionally Irish (my husband is of Irish heritage so he loves it)... however when I text the name to someone, her reply was "it sounds like semen"
So yeah, it won't get pronounce correctly and I can't quite get past that.

I don't mind Seamus, but my husband loves it. I just can't get past the spelling. It can be confusing to pronounce...

I had no idea Seamus was a variation of James! I first heard it as SHAW-mus, but maybe that's wrong. Anyway, I prefer Sean personally, but Seamus is fine too
