If the names are too close (like
Mary and
Marie or
Michael and
Michelle) then I dislike that. If they're similar meanings but don't sound alike, then that's fine because chances are the only people who would notice same meanings are those of us who are obsessed with names :-)
My twins would be:
Juliet Christine and
Lily MariahJayden Christopher and
Jonathan NicholasJayden Christopher and
Lily Juliet
