Yes, I do know what the documentation is though I have not seen the original documents for myself. One researcher that was in contact with me, sent for a copy of the chancery suit that was brought by Robert's son, Rueben, after Robert died "intestate" in 1823 at his home in Berkeley Co. Robert's will was probated in Fincastle, Botetourt, and Berkeley Co's in Jan.,1824 but Rueben brought the suit against his mother and the other 9 children, to force the division among the heirs of Robert's land. The researcher hired a man who is part of the Historical Soc. (as I remember) to copy it for her and she has sent me a copy also. George Washington FILSON was (according to the information sent to me by Larry FILSON) prob. the 3rd son (but perhaps the 1st) of Robert FILSON and Mary CAMPBELL. His information states that he was b. c1776 (or just possibly 1770). He m., moved to Ross Co., OH. and then moved to Vermillion Co., IN. He had many descendants.Is this the correct George W. FILSON that you are talking about?There are also tax records and other land records but I do not have the locations of those in VA.; they are spread in more than 2 Co's.
