Oh I think you're totally right about either going for the older English names, classical greek and latin ones or norse ones. The hilarious part is that I think they end up sticking out more, because people don't use them anymore (or do something horrible like add extra/replace letters with an extra "y" or "k.")

We went Scandinavian for our son, just because there were so many Aidens out there. I can see why, it's a cool name, but there are like three or four Aidens in my son's pre-school right now. Your poor brother lol.
