Irish Name spelling - asking those with Irish knowledge

[birchygoo]

we have settled on a boys name and we love Cahir. However we have been looking at alternative spellings.

Cathair - which I like until it is broken down into Cat Hair (which I know will happen in school

Cathaoir - which is chair - I cant call him chair!

Any thoughts on a preference - will be said in Ulster dialect.

I actually know Cahir H*aly and it's definitely Ca-her ;), lovely chap btw, that's the only spelling and pronunciation I know ( other than the actual place Cahir, which is pronounced Care)

The hurler I mean I know, not the politician, never heard of him!

Cahir is fine. I know 2 spelt like this.

If it's any use, I have a Ciar, pronounced the same as Keir. It's like the first part of Ciaran, we left off the "an" as it means little and he wasn't going to be little. I like Cormac too.
