Old/ unusual Irish boys names

[Wapawapa]

We are Irish living in Ireland and considering an Irish name.
Not one of the "common" names like Cian, Sean, Liam, Cillian, Peadar, Micheal , Fiachra, Conn, Fionn, Oisin, Naoise etc

Not one of the ones that have become popular recently as family/ friends have got there first!
Eg Odhran, Rian, Tiernan, Tadhg

We are thus leaning towards an unusual/ old name that is not commonly used. I will get a book but as the weekend is coming up I'd love to have a few suggestions

(Excuse my lack of fadas!)

Hope you're finding inspiration in this thread anyway @CycloGoose

I am finding inspiration here and the debates are interesting. Thank you all for the suggestions

Breifne is nice

I love Enda. I know a few that would be in their forties but no babies or small children. It must be due a comeback.

Is Ruairí too common?

Enda
After the sh*t Taoiseach ?
Nope !
Wasn't there a St Mel / St Mél ?
I think the cathedral in Longford is named in honour of him.
It's a nice name.

I love Daithi, I'd just it but I know an older one who is an ejit. A child one though who is a lovely, fun little guy
