S. Bell,
You asked where in Barnwell Co, S.C. the lines were.
Marie ALLEN was born in Dunbarton, Barnwell County, South Carolina. I know the town isn't there any more.
Her parents show on her death certificate as Jim ALLEN and Lila GOMILLION.
Marie's husband named Cudger COURTNEY his death info given by him as informant on the hospital info shows he was born Bonneville, Orangeburg County, South Carolina in 1896.

There is no living children to help with any info. I can't find to much before this really. I have missing pieces to the puzzle I do have some census info. Going by census I've found I believe Cudger COURTNEY's grandfather's name is Isaac COURTNEY born abt.1820 South Carolina married what looks like a 2nd wife named Peggy.
Not enough AA searching any lines to help make connections..know what I mean? I have been posting everywhere.
Sorry so long.
Thank You,
Theresa
