Adam de Port

Adam de Port (d. after 1174) was an Anglo-Norman nobleman and Baron of Kington.

Adam was the son and heir of Roger de Port, who died before 1161, Through his possession of the manor of Kington in Herefordshire, he was considered by I. J. Sanders to have been the baron of Kington.

Adam forfeited his barony in 1171 for treason, for attempting to murder King Henry II of England. The medieval chronicler Roger of Howden claimed that Adam was exiled in 1172. No other details of the plot are known. although he was fined in 1175 £200 by King Henry.

Adam's lands were held in the royal demesne until the reign of King John of England, when they were divided up amongst several noblemen. The lack of protest to the division strongly implies that Adam had no heirs that could inherit.
