I think
Leah,
Lea, and
Leia will all be mixed up at some point. The names are just too similar not to be.
I'm an oddball and inwardly pronounce
Leia like
Leah, but because of
Star Wars would outwardly pronounce the name as LAY-ah. I don't think it's "too"
Star Wars; I just think that
Star Wars made an uncommon name not so unheard of anymore.
I actually just put
Leah on my PNL the other day and was this close to adding
Leia but decided against it because of the pronunciation differences even though I prefer the spelling of
Leia over
Leah.
