CHENEY, Ebenezer and Abigail Thompson, Mar. 18, 1760.
↑ The Royalston family register for Ebenezer says after recording his death that he had 19 children in total. Records for 18 have been found. The Cheney Genealogy, adds a son Simeon, bp. 29 Dec 1767, "d. in infancy". This is only four months before Joanna was born and baptized a week later. The Mendon church records are not online and the Mendon VRs do not list this baptism though it does seems to include some baptisms from the church records, so it has not been possible to see if this is a mis-transcription, an error, or just as represented.
