I'm searching for proof that wife, "Abigail" of Thomas Meredith, Sr was really Abigail Neeley, dau of Richard Neeley and Ann Moberly/Mobley.

Thomas Meredith, Sr left will in Fairfield Co, 1808, names wife, Abigail. Thomas Meredith Sr and family move to MS and he is killed by Indians there in 1812. His will filed in Amite Co, MS, 1813 by widow Abigail.

Richard Neeley left will in Fairfield Co, SC, 1793, proved 1799. He names among others, dau Abigail.

I have found no marriage record or any document stating the surname of wife Abigail in SC or MS. Can anyone help????
Will gladly swap info and source documentation.

thank you, Susan
