He mar 22 May 1786 to
Caroline Medkaff [born 1768 or 1769].
She was the illegitimate daughter of the 10th Earl of Pembroke.
The 10th Earl paid for her and took an interest in her welfare, and he and his family stayed in touch with her.
John and Caroline married at St. Bride's Church, London. See mar entry from here.
John and Caroline lived after marriage at Dropmore Hill,
near Burnham, Buckinghamshire.
They are living at Dropmore Hill in 1787.
The 1790 codicil of will of 10th Earl makes provision for her. He seems to call her "Carolina".
Dropmore Hill was sold in 1791.
They moved to London.
In the 1793 codicil to his will, the 10th Earl explicitly says Mrs. Williams is his daughter. Though he calls her "Catherine".
Herbert letters in [Pembroke Papers, vol.2] discuss John possibly taking Holy Orders. But it seems this never happened.
Instead he entered the customs service.
John's will says he is "one of the Commissioners of His Majesty's Honourable Board of Customs in London".
His will dated 22 [Nov or Dec] 1817. Codicil 19 Aug 1822. He is of Clapham, London. It mentions an annuity paid to his wife by the Earl of Pembroke.
He was bur 1 Nov 1827 at Holy Trinity, Clapham. See index.
Will proved 12 Nov 1827.
dated 17 Mar 1841.
She is of Stanmore, NW London.

Caroline Williams, age 75, was bur 24 Jan 1845 at Kensal Green Cemetery, London. See index.
Her will proved 31 Jan 1845.
They had issue:
William Grenville, 1st Baron Grenville
purchased Dropmore Hill in 1791.
It was then a house on 30 acres.
See [Wood, 2019, p.61].
Grenville wrote in Jan 1792 that it was tiny: "It is so literally a cottage (having originally been inhabited by a labourer, as such)". See [Wood, 2019, p.68]. But this probably says more about Grenville's privileged background than about the house, which does after all appear and is named on the map.
Grenville built the huge Dropmore House on the site in the 1790s.
