I voted Kayla! One of my best friends name is Kayla and I think it's such a pretty name!! If my last name didn't start with a c (but pronounced as k) i would consider it too =) And my last name is brazilian, so that would probably sound really weird together =)
as of the other names:
tiffany: i never liked that name - always associate it with someone arrogant...i don't know why...but when i hear tiffany i picture this self-absorbed "pink" girly-girl....sorry :/ but i mean in the end YOU need to like the name, not me
brooke: i think it's really pretty! would have been my second vote
tia: i think it sounds kinda pretty, but i'm not such a big fan of it, since i'm brazilian and in portuguese tia means "aunt"... so for me tia is a weird name for a child
isla: basically the same thing...isla is spanish for island...i mean the pronounciation is different...but still...at least i think so? how would you pronounce isla? is it pronounced like ayla? cause i really like that name
so in case it's the same pronounciation i would prefer ayla! i love that name (funny how much the spelling actually matters....)
zea: cute name, but not my favorite =)
kiani: beautiful name, though i would probably prefer a different spelling again =)
elisha: i imagine a bubble-gum chewing brat
i don't know why
but i like alicia, which is "similar" =)
