Norton’s background is obscure, although he may have been a kinsman of the King’s servant, William Norton, who was granted various annuities in the late 1370s on becoming blind.
Over the years Norton added to his holdings in Westminster. During the Easter term of 1390 he and his wife bought the reversion of a messuage and appurtenances there: they had entered this property, together with another messuage and five shops, by Michaelmas 1405, when they leased the premises at a rent of 20s. a year to William Norton the younger, who was probably their son. The couple also owned a modest estate in the country. In 1412 they conveyed farmland and buildings in the Shelford and Great Bardfield area of Essex to Richard Alfred and others, who either bought their title outright or, as seems more likely, held it as trustees. Nine years later the Nortons were confirmed in possession of lands and rents in Paddington, but there is nothing to suggest that they owned property on a large scale.
In January 1390, one year before his own return to Parliament, Norton attended the Middlesex county elections and offered personal guarantees on behalf of John Shorditch I, one of the newly returned shire knights. He is also known to have been present at elections to the Parliaments of May 1413, November 1414, 1417 and 1422, although the William Norton who witnessed the return of 1432 was almost certainly the kinsman and namesake upon whom he had previously settled his Westminster properties.
