I don't like matchy twin names. Or even matchy not twin names. Individually I like
Jamie (boy only) and
Janie as nicknames. Out of the non matchy ones I think
Jason and
Madelyn is cute, but I'd like to see it spelled
Madeline or
Madeleine. I'd also like
Katelyn if it were
Caitlin. I just don't really like any of the other names.
