Hi Alex,
The only thing she knew about where Caldonia was buried was that she's buried in Gregg Cemetery near Tracy; her grave is unmarked. I've been to Gregg. It's a little hard to locate, but it's a nice little cemetery and well taken care of. Some of the Andersons are buried there also. I tried to get a death cert for Caldonia, but didn't find anything.
Caldonia's father was George Washington Harris. His wife was Martha. Another descendant who lives in Sequatchie told me that Martha's maiden name was Smith and that she was the daughter of Elias Smith. I'm also descended from Elias Smith on my father's side. I have not found any indication that Martha was his daughter. There's a lot of confusion surrounding Elias and his many wives/children. I can give you more about that if you want to email me or send me a note on Facebook.
Next time I'm down for a visit, we need to get together and compare notes. Give Aunt Maggie Lou a hug for me when you see her next :)
Donna
