Love it! I've got friends with a Chay (pronouced Shay) and that's cool, but I think the Che spelling is cool. As for mispronunciations, well people say Sill as for Silas, I get Nelly when it's Nelle, and my dh gets called Random (and trust me that's not his name! ). If you like it - then go for it, you will never get EVERYONE to like it.

The only thing we've done with our names is that if we feel one is a bit more unique, then the other name is slightly more mainstream, so our kids can choose what name they want to use if that's ever an issue. Not that I think it ever will be.
