Yes, I'm doing nano-prep.
Of course there are all the Biblical names and the more common names you get today. The girls' names are always stranger than the guys names, but here are some that I have in the ol' family tree:
Alden, Alon, Eulon, Elon, Isham, Melvin, Levi, Beauregard, Menoah (went by Noah), Lavender (went by Lav), Alvah, Leander, Emory, Flake, Mickleberry, oh yes and a couple of funny first and last combos like Sledge Hammer and Jack Hammer (brothers in the hill country of Texas). Forrest is another one (My dad was a Forrest Henry Jr. from Mississippi). Two good nicknames for Forrest are "Woody" and "Trees." Then Absolom, Ptolemy Philadelphius, Prentice, Lafayette, Clell, Drayton, Elmer, Elvis (my great grandfather had twin brothers named Ellis and Elvis in Mississippi), Alford, Felton, Columbus, Grover, Zebedee, Asa, Hollis, Bartholomew, Bartlet or Bartelott, Lemuel, Hilliard, Orman (I have a cousin named Orman - he goes by his middle name), Carroll, Greenberry, Anderson, Ashberry, Archibald "Archy", Ezekiel "Zeke", Charles Virgil, Farish, DeWitt Franklin, Francis Marion, Micajah, etc. My greatgrandfather's name was Osceola Johnson. He went by Oce until the 1940's when he changed is name to Otis Berry.
Anyway, you get the idea.
As for using last names as first names, it was *very* common in the South. So was having a president's name like Jefferson, Taylor, Madison, Washington, etc.
One name I found... Sherman Tecumseh (first and middle names) - NOT a southern name, but interesting nonetheless (I have no idea how this person got into my family tree. The vast majority of my family was in the TN, SC, NC, MS, and VA areas).
