FamilySearch ID: M1H8-LPQ.
FS has her the daughter of Thomas Powell (1616-1681) but given the confusion over the two named Thomas Powell in Connecticut, I'm reluctant to give her that parentage. Her marriage to John Townsend in 1664 and first to Thomas Tuttle in 1661 is also questionable. The FS records have Tuttle living until 1710; John Townsend until 1709.
Hannah married John Townsend II, son of John Townsend I and Elizabeth [Montgomery]. (John Townsend II was born in 1640 in New Amsterdam and died after 1715 in Jericho, Long Island.)
