I do not have Don or Brown Agnew, but I suspect that they may descend from Andrew Agnew b. 1779 and his wife, Ann Caldwell.Most of the Agnews descending from Samuel b. 1738 in PA are Presbyterians, but Andrew and Ann were Baptists.They are buried in the Turkey Creek Baptist Church cemetery in Ware Shoals, Pickens Co.Only 1 (Samuel b. 1799) of their probable 9 children (8 sons, 1 daughter) seems to be documented.With all of those undocumented sons, one of which I believe is my ancestor Elijah b. 1810 to 1820, there have to be a lot of SC and southern Agnews who descend from Andrew and Ann.
