Do you have access to census records?There is a GeorgeScarborough in Jackson Co., LA on the property of Irwin (Irvin) Scarborough in 1850 with his sister Martha. I am fairly sure that G.P. is the son of Irvin. A DNA test would verify whether or not descendants of G.P. match the DNA of Major James Scarborough descendants.
