The career of Wynnesbury raises problems. According to the earlier biography the MP married Joan, heiress of the manor of Pillaton Hall in Staffordshire, as early as 1393, and left by her a son and heir, Hamlet, improbably said to be only 30 years old ‘and more’ on Joan’s death in 1450.
The MP’s identity is rather to be found in a more important man, John Wynnesbury of Glazeley, who appears alongside Hamlet in the Shropshire subsidy returns and cannot have been his father. A pardon of 1464 and a deed of 1479 demonstrates that the manor of Glazeley and other Shropshire property passed from him not to Hamlet, who died in 1473, but to a daughter and heiress, Margaret, wife of Fulk Sprenghose of Plaish (Salop).
This John Wynnesbury was survived by a widow named Elizabeth rather than Joan. In January 1452 two yeomen of Bridgnorth are said to have hunted illegally in her park at Glazeley; and in 1459 she was sued for debt as the executrix of her late husband’s will.
The daughter had a troubled marital history. Before 17 Dec. 1453 (and probably some years before) she had married Fulk Sprenghose, but the marriage encountered trouble. After the death of William Burley I* in 1458, Sprenghose, who numbered among the powerful Burley’s servants, abandoned her in the hope of contracting a marriage with Burley’s widow, Margaret Grey, who had an extensive jointure interest in the Burley lands. Our MP’s daughter resisted her desertion, securing a verdict in favour of the validity of her marriage from the archbishop of Canterbury, but Fulk’s appeals to the papacy left the matter unresolved as late as 1468.
Aside from these revisions, there is little to add to the earlier biography. It seems that as a young man Wynnesbury campaigned against the Glendower rebels in Wales, serving between 1404 and 1406 in the retinue of Thomas Neville, Lord Furnival.
Although not a member of the quorum, Wynnesbury was one of the most active of the county’s j.p.s. Between June 1435 and June 1439, for example, he was present on all 17 days for which the j.p.s were paid for sitting.
