I love the name. I feel like MAD eh line is the correct/proper pronounciation for
Madeline. After all
Carolyn and
Caroline are two different names that are pronounced different. I like the MAD eh lyn pronounciation a little more so I would go with the
Madelyn spelling. (This is just me. I think most people say MAD eh lyn for both
Madeline and
Madelyn).
I personally would only consider it for a middle name just to avoid the possibility of a
Maddie.
I don't actually know any but my sister babysits for one who is under 5, a radio dj I used to listen to has one who is 2 or 3 and
Madelyn Gosselin, I know of. I don't know how they spell it though.
