I think the last one is interesting, never saw or heard of it before, "O Riegaine" (no fadas it seems). How would that be pronouced in Irish? Stumbled across it here at: libraryireland.com/names/or/o-riagain.php Could I choose to use that spelling of "O'Regan" if I wanted to, is it "legitimate" and acceptable to do so?
Is "O Riegaine" even Irish actually?
By the way the second part of my surname isn't Irish, it's Slavic - can a Slavic surname have an Irish spelling I wonder? You know, how we Gaelicised some English surnames (at least I think we did/can), could we do the same with a Slavic surname?
Thanks.
P.S: my better half told me my posting history makes me look a bit mental (ha, what does she know! lol), if you check my profile you'll see my paranoid conspiracy nut side and my rather argumentative side but ignore all that, I go argumentative sometimes for the hell of it, lol. Not a troll, just, well, like a good 'aul back and forth
