My Great-Grand Aunt Fannie McCaskill was born 1901 in Lee County, SC. Do you have additional information on her? I see that you mentioned Texas; and I know some of the McCaskills in my family migrated to Texas. I would be curious to know because if she is my Fannie, she is my Great-Grandfather Logan McCaskill's daughter.
Also, is your "Fannie McCaskill" African-American? If so, she was Mulatto.
Please let me know if we're on the same blood lines. If not, well it was worth a try:-).
