Hello lovely community! I would appreciate your thoughts on a name I have in mind for my baby boy.

The name is Costello.

Its a fairly popular Irish surname (BTW I am Irish) and numerous articles online suggest it is a first name too, but Ive never come across anyone with it as a first name.

That got me wondering if Costello as a first name is a terrible idea?

Or is it just the case that its not that popular yet?

What do you all think? Cool first name? Or bad idea?

Thanks in advance for your feedback.

I'm sorry but I don't like it (and I'm Irish). There are a lot of lovely Irish names for boys but I don't think it works as a first name. The first issue with it would be where to stress the vowel? Like the way Irish people pronounce it in Ireland or the way it's pronounced in the name Elvis Costello. Conall is a nice c name.

Wow that message is really quite rude. I am actually Irish so please don’t be so presumptuous.

I kindly asked for opinions, not rudeness

That is an opinion, if you only wanted positive ones you should have stated. It gives me that kind of impression too.

Makes me think of https://www.costco.co.uk/

Not cool. Bad idea.

No, not good. Also, I'd point out that if OP is Irish in England the pronunciation will do her head in.

The pronunciation of Costello in Ireland (at least in my part of the country) is with the emphasis on the first syllable, so 'COS-tello'.

In England it will usually be pronounced with the stress on the second syllable, so 'cos-TELL-o', as in the singer Elvis Costello.

Either way it's not good.

Yes, I was also wondering about this OP.

Where do you want the emphasis?
Where I am in Ireland it’s always said COS-tello as pp mentioned. The emphasis is on the first syllable. Is that the pronunciation you’re looking for?
It’s sometimes spelt Costelloe too.

I’m not a huge fan of the name as a first name. Maybe I’m just not used to it.

How about Flanagan, Boyle or Mahoney, @CookieMonster2025 ?

NewMarmiteJar · 10/03/2025 14:55

It's a nice word but not as a first name, sounds silly.

CookieMonster2025 · 10/03/2025 19:08

Thanks for your opinions and different thoughts on pronunciation!

Despite people saying its silly, I still like it! So at least I know now that my thoughts on the name are strong. Name preferences are so personal.

I don't like Costello as a first name.
How about Colm or Cormac?

They are indeed! Go for it if you love it.
I like it as a surname, but personally think it doesn't sound great as a first name, and I love most Irish names.

My cousin has a son named Castello and he's often referred to as Cas. It works as does their adds even more unusual name.

My DS has a friend named Cassidy. Very similar Irish surname vibe.

I quite like it! It’s different without being bonkers and it’s cool.
Give him a sensible middle name and if he decides he hates it he can use that.
Or if you’re unsure use Costello as a MN?

Dustmylemonlies · 10/03/2025 20:15

I normally hate these 'out there' names but weirdly like this one! I think it depends on the surname though. It is a mouthful so would probably work best with a one-syllable surname though.

HundredPercentUnsure · 10/03/2025 20:25

I taught a boy called Costello about 3 years ago, he'd be about 8 now. It suited him.

I'm not a fan of Costello personally but if I loved it then I'd absolutely use it a first name.

CookieMonster2025 · 10/03/2025 20:31

Thank you 😀

I love it, but I suppose it may depend on your surname.

Berlinlover · 10/03/2025 20:42

I love it but the only place where it’s pronounced correctly is in Ireland.

JustsoyouknowImnotlying · 10/03/2025 20:59

I'm sorry @CookieMonster2025 but I think it's a terrible first name. Do you live in Ireland? (I am Irish, in Ireland) I just don't think it works. I suppose it depends on your surname too...

CookieMonster2025 · 10/03/2025 22:07

Well Ive decided that I like it despite what other people think so i am glad I asked 😀i think so many popular names are fairly terrible and would never dream of calling my child oscar or james or something, but if i actually met someone with that name I wouldn’t have any aversion or anything to them! I think we analyse names differently when its abstract vs when we actually meet someone with a name

Not a fan. Difficult to shorten if you want to. It’s either Cos or Tel I guess.

I think, as pp said, three syllables plus surname, if that’s more than two, could be tricky.

Costsa-del-Tel

Sorry Op. no.

Jessieshome · 11/03/2025 16:43

I really like it, but I wouldn't be able to use it amongst my family and friends as I know, just about everyone I know, particularly my dad, would call him Elvis!

I'm glad you are sticking to your guns, call your kids what you love (as long as it's not too bonkers!). One of mine has a well known name but very rarely used and is more of a surname than a first name, after the initial shock and curiosity wears off, it just becomes totally normal, it just becomes them, and people forget it's 'unusual'. And like you say, I'd much rather have a Costello, than a Theo, Jack, Harry etc!
