Thanks for posting the details, Amondg, and apologies for saying my daughter-in-law's ancestor, Jane was James and Sarah's daughter, she was actually their grand-daughter b.c.1858 Theydon Bois, daughter of James and Sarah's son, James and his wife, Mary Ann (?Andrews).
Interesting about William and Hannah, having children in the same period as James and Sarah, as a Hannah Hagger was a witness at James and Sarah's marriage.
Thank you too for your comment Chooch. Did John (1820) stay in the Epping area?
Regards, Steve
