• General Notes

  "John de Cherleton (the second of the name) had livery of his father's lands.  In 33 Edward III, being lord chamberlain to the king, he was in the wars of Gascony, in attendance upon the Black Prince. He was summoned to parliament from 15th March, 28 Edward III (1354) to 20th November, 34 Edward III (1360) as "Johanni de Cherleton". He married Maud, the daughter of Roger Montgomery (all other occurrences in the same source say Roger Mortimer), first Earl of March. John de Cherleton, like his father, had not the designation of 'Powys'
  in his summonses to parliament; but in several State documents to which he was one of the witnesses in 28 and 29 Edward III (1354-5) he is termed "Johannis de Cherleton Dominus de Powys" -- for instance, in the two charters dated at Roxburgh on 20th January, 1355, whereby Edward (Balliol), King of the Scots, resigned his crown and realm of Scotland, and the dominion of Galloway to the King of England. He was deceased on August 30, 1360. An inquest held at Welshpool on 7th September following, found him to have held the lands and
  tenements of Pontesbury and Charleton, the castle and manor of La Pole, the manors of Botiton, Talgarth, Watrawell, and Walwerne, the lands, etc., of South Tradmarchel, South Lanverhudel, Kereynon, Keveylloke, Megkeine, Iscoite, Megheine Uscoite, Trewerne, Teyrtrefe, and Meghnante, the cantref of Arwistly, and the manor of Penpree. John, his son and heir, was twenty-six years of age at Easter (April 5), 1360." [Source 2, pp. 20-21]
