Is anyone researching the Porterfield family that originated in Edgefield County, SC nearby counties of Abbeville and Laurens in the late 1700s-early 1800s and then relocated to various other southern states? I am attempting to establish the parentage of Sarah (Porterfield) Vines (wife of Neely Vines) of SC who moved from SC to Union Parish, LA. One of their sons, Washington (b. 1841) moved to El Dorado, AR where his son Crawford (b. 1884) was a prominent physician. Seaborn Vines (b. 1811), and a sister, Sallie Anne (Vines) Porterfield (b. 1821) moved from SC to DeSoto County, MS. I believe they were siblings of Neely and I suspect that Neely and Sarah are brother and sister of Sallie and ____ Porterfield. They may have been children of John or Robert Porterfield of the old Edgefield district, SC. Any additional information about this family would be helpful.
