Although the Stoctons were an established merchant family in late medieval York, William’s parentage has not been established with absolute certainty. He has been said to have been the son of another William Stocton (d.1441), who married twice but no concrete evidence to support this hypothesis has come to light.
By this time Stocton had married and in 1433 he and his wife, Alice, were admitted to the city’s prestigious guild of Corpus Christi. Alice was the widow of Roger Selby, a spicer and brother of the three-times mayor of York, William Selby†, and the match must have taken place immediately following her first husband’s death.
Stocton became increasingly well connected among York’s merchant elite. In 1435 John Aldstaynmore*, the wealthy alderman and merchant of the Calais staple, appointed Stocton and another merchant, William Holbeck*, as co-executors of his will alongside his brother Thomas Aldstaynmore and another kinsman, Henry Aldstaynmore. John Aldstaynmore evidently foresaw problems, as he appointed a third merchant, Thomas Warde, to give counsel to his executors, and also called upon the senior alderman, Nicholas Blackburn, to oversee their activities.
Stocton had joined the ranks of the aldermen by 10 Dec. 1442, when he was present at the council meeting that decided to review the city’s boundaries, and in February 1446 he was elected mayor of York. On 16 Jan. the following year, shortly before the end of his mayoral year, he was elected as one of the city’s MPs to attend the Parliament summoned to meet at Bury St. Edmunds the following month.
On his return from Parliament Stocton continued to play a full part in the government of York. In July 1448 he was named to the commission appointed to investigate allegations of treasonable words against John Marton. Little evidence survives of his activities during the 1450s, but he continued to attend council meetings and in 1453, and again in 1460, he attested the parliamentary elections.
Some evidence survives of Stocton’s private affairs. He continued to be active in overseas trade, and retained his position within the York Mercers’ Company until his death, contributing towards the costs of their annual Corpus Christi pageant.
Stocton’s family is rather less well documented. His known son, John (a merchant) was admitted to the freedom of York by patrimony in 1446.
