A wealthy London merchant, ‘at the head of the Turkey trade’, Williams was said to be ‘the greatest exporter of cloth in England’.
for his constant attendance, his judicious and faithful discharge and great dispatch of the several duties of that high station, his vigilant care in preserving the peace and quiet of this city, for the easy access he has given to our fellow citizens upon all occasions and more especially for the frequent opportunities he hath given this court of meeting together for the dispatch of the public business.
26 Oct. 1736, Jnl. vol. 58.
On 4 May 1743 Thomas Carte, the Jacobite historian, reported:
Sir John Williams has been for some time languishing of a dropsy and been tapped several times, and his death is daily expected.
Stuart mss 249/113.
He died three days later, 7 May 1743.
