Kingsbury was admitted as a
freeman in Watertown on March 3, 1635/6 and settled in Dedham in 1636. He was one of the 12 men who petitioned the General Court to
incorporate Dedham as a separate town, though they asked for it to be called Contentment. He held various town offices in Dedham, including
pound keeper. Kingsbury was a town proprietor and was elected to the very first board of selectmen in 1639. He served as selectman for 12 years in total. Kingsbury also signed the
Dedham Covenant. He was appointed by the
Massachusetts Bay Colony to
end small causes. After selecting
John Allin as pastor of the
First Church and Parish in Dedham, Kingsbury's name was put forth with those of
Ralph Wheelock,
John Hunting, and
Thomas Carter, to be ruling elder, with Hunting eventually being selected. Some of the land he owned is in what is today
Needham, Massachusetts ==Personal life==
