He was the son of John of Monmouth and his second wife Agnes, daughter of Walter de Muscegros.[2]
Penrhos Castle was the focus of a sharp dispute the younger John of Monmouth had with William III de Cantilupe.[3] There are official records showing that John was appointed custos of the castle in 1251, and William was pardoned the following year for demolishing it.[4] On the basis of documentary evidence, the castle and the dispute it created lasted from 1248 to 1253.[5]
Family and legacy
John of Monmouth died, according to the Victoria County History of Dorset, without issue.[2] He left Monmouth Castle to Prince Edward.[6] His heirs were Albretha de Boterell and Joan de Nevil, an aunt on his mother's side, and a first cousin.[2][7]
A recent scholarly source identifies another John of Monmouth, later hanged for murder, to whom this John of Monmouth left property, as a half-brother.[8] It is stated that John of Monmouth married a daughter of David, Earl of Huntingdon.[9]
