William Lok

Sir William Lok (1480 – 24 August 1550) was a gentleman usher to Henry VIII and a mercer, alderman, and sheriff of London. He was the great-great-great-grandfather of the philosopher John Locke (1632–1704).
Family.
William Lok was the second son of Thomas Lok, a London mercer, and the grandson of John Lok, also a mercer, who was Sheriff of London in 1461. His mother was Joan Wilcock (d. 1512), only daughter of one 'Mr Wilcock' of Rotherham, Yorkshire.
Career.
Even before he was admitted to the Mercers' Company in 1507, Lok had already supplied cloth of gold and silver to Henry VIII. During the course of his visits as a mercer to the annual markets in Antwerp and Bergen op Zoom in the Low Countries, he collected intelligence which he passed on to the King and his chief minister, Thomas Cromwell.
In March 1527, he was granted 'exclusive licence to import silks, jewels, and mercery wares for court revels'. In addition to his trade as a mercer, Lok was involved in other business ventures, including the export of beer. In 1528 he supplied the royal ordnance with six hundred leather harnesses. In 1531 a ship travelling from Chios to London which had been hired by Lok and John Gresham was detained at Lisbon. According to a letter dating from 1533, Lok had at some time visited Crete, and may thus have been involved in the wine or currant trade. The wealth he had accumulated as a merchant by 1535 is indicated by the fact that he was rated in that year, perhaps in connection with a subsidy, at £1000.
Lok and his wife were Protestants, and supported Henry VIII's divorce from Catherine of Aragon. His daughter, Rose Lok, later recounted how he pulled down a copy of the bull by which Pope Clement VII had excommunicated Henry VIII for his marriage to his second wife, Anne Boleyn:
Of my father in Holinshed's "Chronicle" I find this story. In the 25th year of the reign of King Henry 8, being the year of Our Lord 1534, at the suit of the Lady Catherine, Dowager, a curse was sent from the Pope, which cursed both the King and the realm. This curse was set up in the town of Dunkirk in Flanders, for the bringer thereof durst no nearer approach, where it was taken down by Mr Lok of London, mercer. Now I, his daughter, Rose Throckmorton, widow, late wife of Simon Throckmorton, esquire, and first the wife of Anthony Hickman, a merchant of London, reading this of my father, have thought good to leave to my children this addition to it, that for that act the King gave him £100 a year, and made him a Gentleman of his Privy Chamber, and he was the King's mercer, and his Majesty vouchsafed to dine at his house. Moreover he was knighted, although he was never mayor, but only Sheriff of London, and so was never any Londoner before him.
Lok also brought French translations of the Gospels and Epistles from the continent for Henry VIII's second wife, Anne Boleyn.
On 20 October 1545, he was elected alderman for Vintry ward, and on 3 March 1549 was elected Sheriff, and knighted by the young Edward VI. On 10 October 1549, he was among those who escorted the Lord Protector, Edward Seymour, 1st Duke of Somerset, to imprisonment in the Tower of London after his first fall from power.
Death.
Lok died 24 August 1550 at his house in Bow Lane, Cheapside, and was buried on 27 August near his parents and his first wife, Alice Spenser, in the Mercers' Church at St Thomas of Acre in London, where his coat of arms was depicted in a window. His fourth wife, Elizabeth Meredith, was buried there after her death in 1551. 
In his will, he left houses and shops in various London parishes including Bow, Spitalfields, and Cheapside, as well as twelve farms near London, and the Dog's Head inn in Cheapside.
Marriages and issue.
Lok married firstly Alice Spenser (d.1522), an early convert to Protestantism.
He married secondly Katherine Cooke (d. 14 Oct 1537), daughter of Sir Thomas Cooke of Wiltshire.
He married thirdly a wife named Eleanor (d.1546), who was the widow of Walter Marsh.
He married fourthly Elizabeth Farthing (d.1551) who was the widow firstly of a husband surnamed Hutton and secondly of Robert Meredith.
Lok had nineteen children, of whom five sons and seven daughters, all children of his first two marriages, survived to adulthood. According to Sutton, all Lok's sons were mercers, and it is likely that all his daughters were silkwomen.
