The Sedbury branch of the Boynton family springs from the second son of Sir Thomas Boynton (VIII), of Acklam, and Margaret his wife. This son, named Christopher (I), was an executor of his father's will,[1] and is said to have been guardian to his nephew (?) Thomas, son of Sir Henry Boynton in the time of Henry IV.[2] He was also on the Commission of the Peace. In 11 Henry IV (1410) there was a Commission issued to Christopher Boynton and others to inquire into the capture of salmon and fry in the Rivers Humber, Ouse, Don, Aire, Derwent, Wharf, Nidd, Yore, Swale and Tees, contrary to the statute of Westminster, and to punish offenders.[3] Later, in 1414, he was one of those who had to inquire into the report that certain lands, held by John de Darcy, chivaler, and Elizabeth, late the wife of Philip, late Lord of Darcy on the days of their deaths, were more than were specified in the inquisitions taken.[4] In 1417 he was on a Commission concerning walls and ditches in the East Riding of Yorkshire.[5] During the same year he was one of the Commissioners of array for the defence of the realm during the King's absence
