Marcia seems quite dated to me. My dd, Brooke, however, does have a friend named Marcia (mar-CEE-a). Her parents are from India so I'm not sure if that's the Indian pronunciation or just one they prefer. I do like that one much better.
MarcieI like Marcie better. Mostly because I know a little from my church and her name is Marcie. Or maybe it's spelled Marci... either way, I like Marcie better.
