Hey! That’s my sisters name, and I love it, you all are a crappy lot to make fun of a name like that, I think the spelling is unique and beautiful. I’d like to here your names so I can make fun of them!
I know "kae" is pronounced "kay", but I get the overwhelming urge to pronounce it something akin to Kylie. I think Kayleigh is the most sensible spelling for this name.
The pronunciation would be Kæ-lee in my opinion.
