Although not alone among the clerks and officials of the Chancery to be elected to the Commons in Henry VI’s reign (for there were at least eight others), Pemberton was nevertheless unique as being the sole master in Chancery known to have been an MP in this period. He may have belonged to the family of Pemberton living in the north-west of England, for in November 1433 as ‘of London, gentleman’, he acted as mainpernor for Richard and Elizabeth Pemberton of Lancashire then granted at the Exchequer the keeping of lands in the lordship of Denbigh. Other members of the family were expected to take the oath against maintenance as administered in Lancashire a few months later.
Pemberton’s long association with Walter Green* and his family may suggest links with Staple Inn, which came to Green on his marriage to Elizabeth Warner. His friendship with the Greens had begun by 1443, when along with Robert Oppey, another clerk of the Chancery, he was enfeoffed of the couple’s manor of Bonhunt in Essex and land in Middlesex at Hadley, Enfield and Barnet.
Even so, the connexion between Pemberton and the borough he represented was slight, and he was only called ‘of Southwark’ on occasion. In July 1454 he was associated with William Bridges II* and Thomas Went*, two local burgesses, as a co-recipient of the moveable goods of Robert Smyth of St. Mary Newenton, and that same year he and the London vintner who shared his name were both appointed executors of the will of Adam Levelord* of Southwark, one of the coroners of Surrey. Pemberton’s links with the borough are also suggested, albeit tenuously, by his presence there in February 1463 when a deed concerning lands in Norfolk was acknowledged before him in his capacity as a Chancery official.
Following his Parliament he continued regularly to receive gifts of goods and chattels,
Meanwhile, following the victory of the Yorkists at Northampton in July 1460 and the appointment of their supporters to the great offices of state, Pemberton’s career in the Chancery was unaffected by the change of regime. On 6 Sept. he was associated with the new treasurer, Henry, Viscount Bourgchier, in a gift of goods and chattels from an Essex esquire,
The evidence suggests that Pemberton was a trusted royal official whose prominence as a master in Chancery brought him into contact with a wide variety of people. In 1461 he had been named with the bishop of London and the treasurer of St. Paul’s, as well as William Nottingham II*, the King’s attorney, as an executor of Master Richard Ewen, the archdeacon of Lincoln. Ewen did not die until 1464, and the bishop and treasurer then declined to take on the will’s administration, leaving Pemberton, Nottingham and Ralph Beere* to pursue the testator’s debtors in the lawcourts.
No evidence has been traced to show that Pemberton was ever ordained priest, although he may have taken minor orders, for he was called ‘chaplain’ when he became a canon of Wells in 1462, and was a ‘canon residentiary’ ten years later.
