William Cromer

William Cromer (occasionally also spelt Crowmer) (1386 – January 1434) was an English Sheriff and Lord Mayor of London and a Member of Parliament for the city.

He was described as the son of John Cromer of Aldenham, Hertfordshire but was probably originally from Cromer, Norfolk. By 1390 he had settled in London, where he became a prosperous merchant.

William had a son also named William Cromer in 1416 who became the High Sheriff of Kent in 1444.

He was Warden of the Drapers Company by 1394, and again in 1428–29. He was appointed Auditor for London for 1399-1400 and 1409–11 and elected an alderman of Billingsgate Ward by 1403 until after July 1420 and of Candlewick Ward from 1420 until his death. He was elected a Sheriff of London in 1405–06 alongside Henry Barton and Lord Mayor of London for 1413–14 and 1423–24.

During his public life he benefitted from a number of profitable commissions from 1407 onwards, when he was also elected to Parliament as member for the City of London (1407, 1417 and May 1421).
