These are my ancestors too and I have been looking for their ancestry.
William and Charity Gatteys/Gattis had a daughter named Nancy Jean/Jane Gattis born 1826 in TN. She married James Allen Cook born 4 July 1819 in Wayne Co., TN and died 18 Nov 1895 in Tyler Bluff, Montague Co., TX, s/o Christian Cook and Mary Coble.
Nancy Jean Gattis and James Allen Cook had my g g g/f Thomas Christopher Cook b 14 Sep 1845 in Tishomingo Co., MS and d29 Sep 1931 in Elmore City, Gavin Co, OK.
If anybody can add to this or make comment, alot of people would be very happy.
