Case Ann Sergeant v Heir(s) of William Bays, Chancery Record Index #1836-007
Papers from this case file clearly state there were 9 children and it lists Elizabeth, the wife of Joel as one of those 9. The 9 are: Charles Bays, John Bays, William Bays, Peter Bays, Elizabeth Bays (wife of Joel), Sally Barker, Anney Sergeant, Rebecca Gray, and Mary Cody. Charles Bays and Mary Cody did not take a share of the estate as they had received some property earlier according the the court papers which explains why there were only 7 shares in the settlement of the estate.
