I saw it spelled Cheyne on television the other night. I thought it would be prn Chey-nee when I saw it (like the US vice president's last name), but then, someone on the show called him "
Shane". I know the spelling for sure because it was one of those reality type shows where they actually put the name on the screen. Chey / Chay would work there, but it's a stretch because of the SH v the CH sound. I don't like the Cheyne spelling anyway, but just mentioning it.
