I have Robert Lancaster b 1776 in Orange County, VA, m 4 Oct 1801 in Jessamine County and dying between 1850-52 in Fayette County, KY age 74. His wife was Nancy Booth b 1774 in VA and d 28 Aug. 1852 in KY. They may be my ggggrandparents. I have to prove a link between them and Ellis Lancaster married to Susannah A Perkins. Ellis was born c 1808 in Fayette County. Any help would be appreciated.
