John of Gloucester

John of Gloucester (or John of Pontefract) (died 1499?) was a son of King Richard III of England. John is so called because his father was Duke of Gloucester at the time of his birth. His father appointed him Captain of Calais, a position he lost after his father's death. He seems to have been held in custody at some point during the reign of Henry VII and may have been executed around 1499.

The identity of John's mother is not known, nor is his date of birth. However, since Katherine, Richard III's other illegitimate child, was old enough to be wedded in 1484 and John was old enough to be knighted in September 1483 in York Minster (when his half brother Edward, Richard's only legitimate heir, was invested Prince of Wales) and to be made Captain of Calais in March 1485, most historians agree these 2 children were fathered during Richard's teen years. There is no trace of infidelity on Richard's part after his marriage in 1472, when he was around 20.

Dr Ashdown-Hill suggests that John was conceived during Richard's first solo expedition to the eastern counties in the summer of 1467 at the invitation of John Howard and that the boy was born in 1468 and named after his friend and supporter. Richard himself noted John was still a minor (not being yet 21) when he issued the royal patent appointing him Captain of Calais on 11 March 1485, possibly on his seventeenth birthday.

An order referring to his appointment as Captain of Calais calls him "John de Pountfreit Bastard." Because of this, it has been suggested that he was born at Pontefract. Michael Hicks has suggested that John's mother was Alice Burgh, who was granted an annuity of 20 pounds when Richard was at Pontefract on 1 March 1474; the grant states that it was made for "certain special causes and considerations." Another candidate is Katherine Haute, who Rosemary Horrox has suggested was a mistress of Richard and possibly the mother of Richard's illegitimate daughter Katherine, who married William Herbert, 2nd Earl of Pembroke. Horrox notes that Richard granted Katherine Haute an annuity of five pounds in 1477. It is unknown, however, whether Katherine and John had the same mother. They were both half-siblings of Edward of Middleham, Prince of Wales.

John was one of two persons knighted on 8 September 1483 in York during the celebrations which invested his half-brother Edward of Middleham as Prince of Wales.
