Sorry lads, Dara is the correct spelling of the Irish boy's name- Darragh is the english spelling- the girls name is Daire.
I'm Irish and this is according to my SIL who's an Irish teacher. (I checked with her before calling my son Dara).
Love the name and no one has ever connected it to Dara O'Briain, though that wouldn't be a bad thing for me either.
