Switching gears, it's not uncommon in the South for the first son to have his mother's maiden name as his first name, a convention for which I have a little fondness. Hence boys with the first name of Davis, Custis, Kennedy, Canton, Todd, etc.
We gave it some thought, but my wife's maiden name just didn't have the right "ring" to it when combined with our surname.
Another southern naming convention which was popular (but now out of favor)is double names; Mary Kate, Anne Marie, Joe Don, Bobby Allan, Johnny Ray, etc.
I must admit I kind of like some of those.
