I like
Dara, but I really want to say "DARR-uh" (like
Daria, without the i). Which in itself is odd, since I'm Canadian and we say the first syllable of Sarah/Sara,
Clara,
Lara, and
Tara to rhyme with "share". But there's something exotic about
Dara that makes me want to treat it like
Mara, which rhymes with "star". One of my friends has a cousin
Tara that they say like British people, "TARR-uh", and it's SO WEIRD to hear/say it that way. I mean, I enjoy it, but it feels kind of unnatural.
I also enjoy Dareth, which seems like a totally awesome way to honour Darth Vader on a girl.
Cara is ok - I have a second cousin named
Kara, so it's familiar to me. I definitely prefer the
Cara spelling. We say it "kair-uh" - same pronunciation for both spellings.
