Bridges’ origins are obscure. There is no evidence that he was related to Richard Bridges I*, even though like him he may have represented the borough of Great Bedwyn; nor that he was a kinsman of another William Bridges, who after serving Henry V rose to be Garter King of Arms under Henry VI.
Perhaps more significant for Bridges’ career, however, was his service in the mid 1440s as bailiff of the liberties of the bishop of London in Surrey and Sussex. The success of this appointment may be indicated by the grant of February 1449, made in reversion to him and Bartholomew Willesdon of the Exchequer, of the royal office of bailiff of Burley in the New Forest. Indeed, he may even have come to the personal attention of Henry VI, for in this grant he was not only described as a King’s serjeant (indicating an existing connexion with the royal household), but also as receiver-general of King’s College, Cambridge.
Although the grant in reversion of the bailiwick of Burley coincided with the Parliament of February 1449, it seems more likely that William Bridges, the representative for the Wiltshire borough of Wootton Bassett, was a different man – one who lived a few miles away from the borough, at Highworth. Yet William Bridges of Southwark was probably the person returned for another Wiltshire borough, that of Great Bedwyn, to the Parliament of 1450. The evidence is circumstantial. While the Parliament was in progress in November 1450, this ‘gentleman of Southwark’ acted as a mainpernor at the Exchequer for one of the knights of the shire for Herefordshire, Thomas Fitzharry*, on his appointment as guardian of the temporalities of the bishopric of Hereford.
Without doubt, Bridges’ career was furthered most by the patronage of William Waynflete, bishop of Winchester. From at least the time of the Reading Parliament until 1465 he held the important post of bailiff of the liberties of the bishop in Oxfordshire and Berkshire, a position for which he was well qualified, having performed similar roles for the diocese of London and for King’s College, Cambridge. The latter position may well have been a crucial factor in Bridges’ recruitment by Waynflete, whose close relationship with Henry VI had resulted in his appointment in 1448 as chief supervisor of the works at King’s and at Eton, where he had only recently ceased to be headmaster on his elevation to the episcopate.
By then Bridges had become a trusted official of Waynflete: in 1456 he was described in the accounts of the bishopric as solicitator domini, indicating a role as a financial or legal agent of some kind, for which he received an annual fee of 66s. 8d. He continued to act in this capacity until 1464 or 1465 when he may have died or else retired, his place as bailiff of the episcopal liberties in Oxfordshire and Berkshire being then taken by (Sir) Richard Harcourt*.
The accession of Edward IV appears to have done little to affect Bridges’ career, save for his immediate removal from the bailiwick of Burley, for, having secured the office of controller of customs in the port of Poole in August 1460, he was confirmed in office by the new King in November 1461. Although Waynflete was no longer chancellor and had failed to inspire the trust of the Yorkist regime, Bridges continued to act on his behalf in the early 1460s.
