I love Irish names. I wanted Declan or Deaglan for DS so much but DH vetoed it. If I've known how close DS's birthday was to St. Declan's feast day I might have gotten it by him. Hmmph. It's shooting up the charts here, though, so maybe it's a good thing I didn't go with it.
I'm not Irish (well, no more than a smidge) but I am American and we're not bothered about about things like that. :o
