Wardship and marriage
Roger Corbet was about twelve when his father died and his wardship became a commodity to be sold by the Crown. The History of Parliament avers that his wardship was bought by Charles Brandon, 1st Duke of Suffolk, a close friend of Henry VIII, and that it was probably he who arranged Roger's marriage to Anne Windsor, the daughter of Andrew Windsor, 1st Baron Windsor. The family historian Augusta Corbet documents the Brandon wardship. There is also a record of Brandon appointing George Onslow as steward of the Shropshire estates in February 1514. However, Brandon cannot have held the wardship for long.
It is known that Andrew Windsor himself bought the wardship from the executors of John de Vere, 13th Earl of Oxford, probably in 1514, because a legal wrangle arose 42 years later between Windsor's executors and Robert Wingfield, son of Oxford's executor, Humphrey Wingfield. The issue is clouded by the fact that Oxford died a month before Sir Robert Corbet, so can never have been Roger's guardian. The connection seems to be Humphry Wingfield himself, who was Brandon's cousin, and a lawyer for both him and the de Veres. The
details are obscure but he appears to have engineered the transfer of the wardship to Windsor via the estate of the earl of Oxford. His son claimed that the payment of 950 marks was never completed, to his own detriment, and Windsor's executors could not produce a receipt. However, they denounced Robert Wingfield's claims as merely vexatious, "contrary to all right, equity & good conscience", in a complaint to Nicholas Heath, the Lord Chancellor. Both sides, however, accepted that the purchase agreement was between Andrew Windsor and the earl's executors.
Having acquired the wardship and marriage of Roger Corbet, Andrew Windsor arranged his marriage to his own daughter, Anne, by 1522. Windsor was very rich because he was deeply embedded in the mechanisms of power at Court. As Keeper of the Great Wardrobe to Henry VII of England, he had responsibility for an annual budget running into thousands of pounds and was an important part of the network of his cousin, the notorious Edmund Dudley. He had survived Dudley's fall to continue in office under Henry VIII. He therefore had influence he could use on his son-in-law's behalf.
