John Cass 3'd Richmond & Sarah Kilton of Warwick Intend Marriage August 13th 1800.
↑Allred, p. 159, identifies Sarah Kelton as a daughter of Family:Thomas Kelton and Martha Simmons (1), b. about 1780. The basis for this is unknown as there is no birth record. Her sister Rhoda's age at death gives Rhoda an estimated birth about 1781 squeezing the available space, and given the marriage in 1800, later dates are unlikely. So this seems less than ideal and without basis.
