Yes, Blount rhymes with count, but many people forgo the "o" and pronounce it Blunt. Which if you're from the deep South is correct, but my husband's family is from Philadelphia.

It's also been murderized in a variety of ways, including Blown and Brown. It's really very phonetic. LOL

Yes, to your other point. Apparently, I look like a Susan, because that's been what many people who can't remember my name have called me.
