Thank you again for your help - I think I have plenty to be checking now.
Jane must have died between 1805 and 1807 so will follow that line.
Her son John married Mary Archbold at Embleton (N.Northumberland) who was a sibling from my direct line.
Their children were Robert, William, Jane, John, Frances, Mary Ann, Elizabeth, Margaret and George.
I see some possible connections!.
Cheers.
