Hi Deb,I have some info. which you might be interested in (or not). :)My Thomason family is from the Laurens/Greenville SC area and connected to the Dial/Abercrombie/McMahan/Stuart groups there. In The Dial Church Collection compiled by Sarah Jane Limehouse Armstrong, it has quite a bit on the Abercrombies from Laurens Dist.. Here is some of the info. for you:
Jonathan Abercrombie, Capt. b/30 May 1807 d/12 Jun 1886 in Laurens CO,SC in 1830 m/Jane Armstrong their son: Bartlett Thomason Abercrombie b/16 Nov 1835 d/14 Jun 1900 in Laurens,SC in 1858 m/Lucinda Atwood their son: Seth M. Abercrombie b/24 Sep 1862 in GA d/18 Dec 1942 in OK in 1882 m/Eliz. Huey --------- Mahala McMahan, one of the sisters of my gg grandmother (Anna W. McMahan Thomason) m/John Harris Abercrombie, who is said to have had a large plantation (322 acres) in Laurens in 1897.
I don't know if any of this is of any help to you. I hope so.
