Believed to be a famous son of Hambleton who paid for the Church completed on 15th October, 1292.
“Despite claims that Sir William de Hamelton may have been born in Scotland, evidence in the Calendar of Patent Rolls for 1306 and 1307 indicates that William was born in the humble hamlet of Hambleton near Selby, Yorkshire. William has also been described as ‘the most distinguished native of the Parish of Brayton’ by W. W. Morrell in his book The History & Antiquities of Selby 1867. He was the son of Adam de Hamelton a person of gentil status and his wife Ann.’ Adam is believed to have also been the father of Robert de Osgodby.
During William's life, Hambleton was a manor held by the abbot of Selby. Hambleton lies west of Selby near Thorpe Willoughby. In the Calendar of Patent Rolls and the Nomina Villarum (1315-1316) he is always referred to as: ,/br> 'William de Hamelton'. 'Hamelton' was usually the spelling of the vill of Hambleton in 1200's and 1300's. As he was granted free warren at Habholme just outside 'Hamelton' (1285) and also had a chapel built in 'Hamelton' prior to his death (1307), he is almost certainly to have been born in Hambleton, East Yorkshire.”
