Dorothy and
Theodore - that's good, and a really nice pairing. Most people wouldn't ever know they were kind of the same name!
These are my twin twofers:
Natasha and
Levi (because
Natasha is "ah, satan" backwards, and
Levi rearranged is "evil")
Olive and
Orrin (
Olive is a shade of green, and
Orrin means "little green one")
Philomena and
Ferdinand (family names)
Evelyn and
Isaac (somehow these two names have become linked in my mind, and make me think of vampires. It's weird but enjoyable)
