I should warn you that on this board, neither misspelled classic names nor misspelled tryndee masculine surnames are appreciated...
Now, if you are serious: Do not insert random Ys.
Madison Elizabeth is horrible.
Madisyn Elyzabeth is beyond words.
Madison is way trendy, way popular, a surname, and means "SON of
Maud".
Ava and
Ella are nice, but very popular. I love
Isabelle, but prefer the spelling
Isabel.
Madelyn is horribly trendy and misspelled. I love
Madeline said with a -line ending, but don't love it with a -lynn ending. I can't stand
Imogen or
Phoebe, but there's nothing wrong with them.
