Nicknames are as much a part of Southern life as biscuits and gravy.
I ought to know. I've lived in the South my entire life and I've been the recipient of several of these after-birth monikers. The most frequent, of course, being "Red." That's a given for any redhead.
Jokes about the flaming tresses started early in life and still go on, even though it takes a little loving care (pun intended) to keep them that way today.
Later on, being compared to the most famous of redheads, and coupled by the fact that my middle name is Lou, I wore the "Lucy" tag for a time.
