I am a descendant of David Thomas Self, born 1892 in Lumpkin County GA. In the 1900 census, David's parents are John and Stacy Self. I immediately noticed two things in this record:
one: John is almost twenty years older than Stacy
two: The eldest son, George, is ten years older than his next younger sibling
When I saw those gaps, I began looking for either additional siblings who died young, or a previous marriage for John Self. I found two original marriage records:
John Self and Miss Rebekah Seabolt, dated Jan 1st 1860 in Lumpkin co GA
John Self and Stacy M Wilkins, dated Jun 4 1885 in Lumpkin co GA
My hunch is that these two John Selfs are the same person, but I am looking for more information to prove it.
