Well personally I love the combo Madelyn Rose, but you don't like that spelling, but what about Madeline Rose? (just a suggestion, it's one of my personal faves)
Madeline Genevieve - It's nice, classy and sophisticated sounding
Madeline Josephine - I don't care for Josephine very much
Madeline Emilia - This sounds very pretty
Madeline Ava - This is nice
Madeline Brie - I like this too
I like my favorite would have to be Madeline Emilia, but the others (with the exception of josephine) I think are very nice too.
