'We learn of the death of Mrs. Betts from a letter written by Rev. Samuel Stone of Hartford ... dated Hartford, July 19 [1647]. ... "Goody Bets the school dame is dead with some others." The cause was an "epidemical sickness", probably an influenza or similar respiratory illness.
'... the following baptism is recorded in the [Claydon] Parish Register, ... "John Bet, the sonne of John Bet and Mary his wyffe was baptised the 5th daye of May 1627." As the mother of Mary Betts was named Mary, and her brother, John, this record, found in the town that was Samuel Boreman's early home, can hardly be doubted to relate to the family of his wife, the John baptized being her brother.'
