Back row, left to right:
Uncle Alfred & Aunt Cordy [William Alfred Lamar & Cordelia Cain Lamar], grgrgrgrandpa [Daniel] Wells, grgrgrandparents Francis Marion &Amanda [Wells] Lamar, Uncle Ren & Aunt Minnie [Virginia J. Lamar]  Lauderdale, grgrandparents John Chas & Sarah Ann [Lamar] Perigo.

Front row, left to right:
Uncle Dan [Lamar, married Ida Beard when he grew up], Aunt Della [married Everett Evans when she grew up], Aunt Gertie [Easter Gertrude Lamar married Truman Phillips when she grew up] and the twins, Elvis & Everett [Lamar]  (don't know which twin is which).

My mom identified them for me, so hopefully it's pretty accurate. She thinks the photo was taken in front of Francis Marion & Amanda Lamar's home.
