Many collectors have examples of his work, or when he was in partnership with George Love but Grimwade biographic details are sparse and there is an intriguing mystery which Theatre experts amongst us may be able to resolve .
I believe he may have had a mark in the lost smallworkers register, almost certainly he worked either as a master or a journeyman before his first recorded mark of 6 May 1763
His wife was probably the Sarah Whild who married a John Faux at Saint Bartholomew The Great, London, on 24 Dec 1759
His son, Thomas Thames Faux was baptised at Saint Andrew, Holborn, London, on 3 October 1761.
His parnership with George Love, formed in 1764, ceased in late 1773 on Love's death, Love's will being proved at PCC on 29 December 1773.
The son, Thomas Thames Faux was apprenticed in 1776 to John Wren II of Worship Street, John himself having moved to Worship Street by 1771, perhaps as early as 1767. Thomas never entered a mark as far as I have found although Heale believes he took over at Worship Street in 1784.
John Faux was declared bankrupt in late 1785. He, almost alone of the older major specialist bucklemakers does not seem to have moved with the times and diversify out of buckles. A mistake, as the silver buckle trade shrunk dramatically in the late 1780 and early 1790.
In 1786, and his house, contents and workshop etc were advertised at auction in the Times and presumably sold for the benefit of his creditors.
He then disappears from view until 1 November 1798 when General Evening Post reports
" The Coroners Inquest sat yesterday on the body of Mr John Faux at his house Suffolk Street, Charing Cross., who died suddenly on Saturday evening last [ 27 October 1798] while on his duty at the Theatre Royal, Drury Lane . Mr Faux was formerly an eminent Silversmith . Verdict , died by visitation of God"
Note that he appears to have been able to get a new house, and a job at an important theatre. Did he have some influential friends in Drury Lane to give him a new life ? Details or speculation very welcome !
To complete the story, Thomas Thames Faux married Mrs Rachel Borman, the widow of Allen Borman of Bethnal Green in September 1790 and died in 1802, as Keeper of a House for the reception of Lunatics , (Will proved at PCC 4 May 1802)
Incidentally I think his name was pronounced to rhyme with Hawks, not Doe.
