Working back from my 2ggrandmother Ann Swan 1803 my ancestry now looks like this using evidence from available records and the evidence of the Swan family graves at St Mary the Virgin, Horton. I have left out for simplicity the evidence details but can provide them if anyone needs them.
Generation1
Ann Swan 1803 = William Young
Generation 2(Ann's parents)
Robert Swan (1767) = Isabel Hindmarsh(1775)
Generation 3 (Robert 1767's parents)
Joseph Swan( 1744) = Ann Hindmarsh
Generation 4 (Joseph's parents)
Robert Swan(1698) = Ly(i)dia Turpin(1711)
That's as far back as I've traced it and I'm pretty happy that the info is solid. The Swans had a long association over several generations with Cowpen High House and there was very little variation in their naming policies so names repeat frequently. It also appears that multiple generations of different branches of the family occupied the house and worked the farm giving a coincidence not just of names but of addresses in records. Unless an extremely methodical approach is taken to working the records back it is very easy to get branches and generations of the family intermingled; Roberts who appear to be sons are actually cousins etc. Just to add to the complication, perhaps there were dynastic reasons for it, the Swans seem to have commonly found wives among the Hindmarsh family. They would appear to have called all the female children Isabel with variants so there are numerous examples of Robert Swans married to Isabel or Isabella.
Other trees include Dorothy Gilhespey and Dorothy Rickerby as Swan wives. That may be true but I can't see any evidence for that in my line.
