The survival of a series of deeds relating to the Manstons, a Yorkshire gentry family of minor rank (although the MP’s elder brother, John, had resources enough to be distrained for knighthood in 1458),
Manston first appears in the records in his father’s will made on 6 June 1439. His father had had a legal career of modest success. He was retained as apprentice-at-law by the duchy of Lancaster from 1415 to 1422 and served a term as escheator of Yorkshire in 1419-20. Yet, although he was a manorial lord, he was not rich enough to make any significant provision for our MP as one of his three younger sons. They had to content themselves with bequests of a silver cup and 40s. each.
By this date Manston had been dead for at least five years. In 1459 his widow, Joan, entered into an agreement to marry John Burton of Kinsley, some miles to the south of Manston, who promised to settle on her a jointure of £20 p.a. if he should fall heir to his family lands. The promise, albeit only provisional, of so large a jointure implies that her hand was a desirable one within the lesser gentry world of which she was part.
