Madeleine - I like it. I prefer the spelling
Madeline. Dislike the nickname
Maddie, which is pretty much the only reason that puts me off using it as a first name.
Liora - ok. Interesting/uncommon but still easy to pronounce, nice meaning.
Renata - I dislike the t, I'd prefer
Renee.
Ren is a cute nickname.
Out of the three, my pick is
Madeleine.
