[Note: Prudence the daughter, is believed to be deceased before the 1790 census since mother Prudence is listed in the contract between James, her son, and David, her husband, in 1804, 1805, 1807 & 1809. The 1790 census only lists 2 females, most likely Lucy and Prudence, wife of David. Also, Prudence the daughter is not mentioned in the Baltimore, Vermont records, as is Lucy and Prudence, wife of David.]
