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.

It's a terrible idea.

Gorgeous!

I personally don't like the surname-as-first-name thing, and I'm not sure Costello works as a first name? Is it the sound you like, or the vibe?

Perhaps instead:

Cosmo
Constantine
Conrad
Stellan

Heya! Could you tell me what you don’t like about it please?

It sounds like a surname (because it is). There's a reason it hasn't taken off as a given name.

Apart from Cos, which is daft, there's no logical shortening either, that I can think of. Stella is the only one, but that's very obviously female and I'm assuming you are wanting it for a boy's name? Costello is such a mouthful. Nobody is going to want to be called that for the rest of their life.

I don’t like it personally, feels like a character name not a persons name, but Constantine is lovely and I actually like Stellan even though I haven’t heard it before.

Similar vibe:

Cassian/Caspian
Cedric
Lysander
Evander

Irish C names:

Callahan
Carrigan
Caelan
Cashel
Cillian
Cormac

Fab name. Ime dc with more out there names go on to great things.

EmiliaRuusuvuori · 08/03/2025 11:26

I like the sound of it but I'm not sure it works as a first name.

PrincessOfPreschool · 08/03/2025 11:27

I really like it.i think it's cool, it reminds me of Elvis Costello. Plenty of other surnames are names (Lloyd being just one) so if you like it, don't worry about naysayers.

I like Cos as a nickname. My DS had a best friend called Cos (Greek, short for Constantino) and he was the loveliest boy.

ValentinesGranny · 08/03/2025 11:29

That child is so going to be known as Elvis...

Chunkilumptious · 08/03/2025 11:29

I don't think it works well sorry. I'm not a fan of surnames as first names particularly unless there's a tradition such as in Scotland. Costello sounds a bit faffy without being a first name as well, so just looks like you've picked a random name you quite like the sound of which to me personally is a bit baseless.

I dunno. I wouldn't have said unusable or even close but not the best out there.

Lovely surname so no offence to those with it as their name!

Bellabluea · 08/03/2025 11:30

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?

shoopshoopdedoo · 08/03/2025 11:33

Not keen at all, sorry OP. Works best as a surname.

Darkclothes · 08/03/2025 11:35

I assumed its was Italian or Greek, because it reminds me of Costas.

How many syllables are in your surname? If its 3+, then Costello Surname is a mouthful. Its different, which can be good, and there are worse names IMO.

This comment just made me count the syllables in my own name, 13! 😲

Nearly all surnames as first names are awful, though somewhat less glaring in cultural contexts where there’s a tradition of boys being given their mother’s surname, or another family surname, as a first name. Even if I didn’t think surnames as first names wasn’t generally a bad idea, I think Costello is a particularly poor choice. I would also assume that someone naming their child Costello was part of the Irish-American diaspora, but had no current contact with Ireland at all, the type of person who takes a name off a website and goes about proudly proclaiming it’s because ‘I’m Irish!’, when in fact one great-great grandparent left Oughterard in the 1840s.

And the ‘numerous articles online’ are almost always those dementedly moronic baby names websites that invent mad, wrong etymologies and pronunciations for Irish names. Like ‘Brady’ being a widely-used Irish boy’s name meaning ‘red-haired king’ and the like.

Strokethefurrywall · 08/03/2025 12:02

Costello is fab as a first 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

Bluevelvetsofa · 08/03/2025 13:32

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.

MeAndMyGhost · 08/03/2025 13:33

I like it!

(disclaimer I'm not Irish) but it sounds memorable and cool 😎

If you like it, go for it.

wandawaves · 08/03/2025 13:35

No, awful.

MajorCarolDanvers · 08/03/2025 13:38

Awful

romdowa · 08/03/2025 13:40

I'm irish and hate irish surnames as first names . It's so cringy and American. So many beautiful irish first names out there.

MarmaladeSandwichUnderMyHat · 08/03/2025 13:42

Costello is a great name! Most importantly, if you like it you should name him that

hereismydog · 08/03/2025 13:42

It’s not the best name I can think of but if you like it for your own DS, then use it!

I expect my own DS’ name isn’t to everyone’s tastes (it’s not unusual, but I do see it slated a lot on MN as an ‘old man’ name); we chose it because we like it.
