I'm late to catching up, I was out yesterday. My sister's ex-husband came from an Italian family where it was tradition to name the first born son after the grandfather, so they had a lot of cousins with the same name. I think it would be confusing, but not necessarily strange. My husband's grandfather had the same name as his sister's husband, so they also had two cousins with the same name. Now that I think of it, MH has the same name as one of my nephews, so even though he doesn't want a child named after him, I wouldn't think twice about doing it if he did.
DH is pretty stuck on Amelia for a girl. I like it, too, but I wish it wasn’t so popular.
I've always thought Amelia was a very pretty name! Although Supernatural did ruin it for me a bit with a really annoying character with that name :P I also have always liked Amelie because I do love that movie.
