Thomas of Brotherton was born 1 June 1300 at the manor house at
Brotherton,
Yorkshire, son of King
Edward I of England and
Margaret of France. His mother was on her way to
Cawood, where her confinement was scheduled to take place. According to Hilton, Margaret was staying at
Pontefract Castle and was following a hunt when she went into labour. The chronicler
William Rishanger records that during the difficult delivery his mother prayed, as was the custom at the time, to
Thomas Becket, and Thomas of Brotherton was thus named after the saint and his place of birth. King Edward I hastened to the queen and the newborn baby and had Thomas presented with two cradles. His brother Edmund of Woodstock was born in the year after that. They were overseen by wet nurses until they were six years old. Like their parents, they learned to play chess and ride horses. They were visited by nobles and their half-sister
Mary of Woodstock, who was a nun. Their mother often accompanied their father on his campaigns to Scotland, but kept herself well-informed on their well-being. Thomas's father died when he was 7 years old. Thomas's half-brother Edward, became king of England (
Edward II) and Thomas was
heir presumptive until his nephew, the future King
Edward III, was born in 1312. The
Earldom of Cornwall had been intended for Thomas, but his brother the King instead bestowed it upon his
favourite,
Piers Gaveston, in 1306. When Thomas was ten years old, King Edward II assigned to him and his brother Edmund, the estates of
Roger Bigod, 5th Earl of Norfolk, who had died without heirs in 1306. ==Career==
