Sheffield held several governmental positions and commissions in Lincolnshire, Yorkshire and London, including commissioner of sewers in Lincolnshire from 1485 until his death, commissioner of oyer and terminer in London in 1495 and 1503, commissioner for benevolence in 1500, commissioner for subsidy in Lincolnshire in 1504, 1512, 1514 and 1515, and in London in 1504.[1]
After his first wife's death in or after 1509, Sheffield married secondly Anne Barley or Barlee (d. 1557 or 1558), the daughter of William Barley, of Albury, Hertfordshire. After Sheffield's death in 1518 his widow married secondly Sir John Grey of Blisworth, Northamptonshire, a younger son of Thomas Grey, 1st Marquess of Dorset by his second wife, Cecily Bonville, and thirdly Sir Richard Clement, of Ightham Mote, Kent. Anne (née Barlee) left a will dated 1 October 1557, proved 7 May 1558.[1]
Death
In 1515, Sheffield helped Cardinal Wolsey in drafting legislation but later gave lead to anti-clerical forces in the House, earning him the Cardinal's enmity. In 1516, he was charged with negligence as a justice of the peace and was summoned before the Star Chamber but negotiated a pardon. Six months later he was incarcerated in the Tower of London after complaining against Cardinal Wolsey, and brought before the Star Chamber again, and this time asked the King for mercy. However the pardon was revoked and Sheffield died in the Tower of London on 10 August 1518.[1]
