Maybe I'm wrong about the whole Yvonne thing.
Nah, you're not wrong, Susie! My mother-in-law pronounces her name Ye-von because that's the way
her mother always pronounced it (and she likes the way it sounds better, too). But, technically speaking it should be Ee-von. After all, Yves St. Laurent is not Ye-ves St. Laurent.
It's funny about names. I went to elementary school with a Marcia. And every year on the first day of school the teacher would pronounce it MAR-sha and she would have to correct them, because she pronounced it Mar-SEE-a.
