I am a descendant of their son Robert, born 2/14/1795, died 3/2/1885 in Brown County, Indiana. I take it you are looking from the ancestors of Joseph and Jane? My understanding (derived from the research of others) is that Joseph was the son of John Henderson and Mary (Polly) Bane, and that Jane was the daughter of Robert McGee and his wife Jane. Does this fit with your information?
