What do you think of these for a brother and sister?

YOU are Irish. Great. These are actually really pretty names, I like them. BUT, do you live in Ireland? Because if you don't, it will make your children's lives harder. If you say spelling/pronunciation won't cause any problems, then go for it. I find it sooo interesting how the "mh" in Irish gets to be pronounced "eev" (Like, Niamh, which is pronounced Neeve)
