I hadn't even thought of
Ismael, but that's also only one letter off! I guess since I'm more used to seeing it spelled
Ishmael.
(Almost no one was named
Aidan when my brother and I were growing up, but he was named for one of our ancestors - we're Canadian and our background is mostly English, Irish, and Scottish. Now, everyone under ten is named
Aidan or
Aiden or
Aden or
Ayden or whatever.)
