[1][2] Her father was the son of Warren Lisle, a celebrated customs officer who engaged at sea with smugglers.

William took over his post, searcher of the customs at Weymouth, Dorset, in 1773, the year in which he married Hester.

[8] Horace Walpole wrote to Mary Berry of "my nieces the Lisles" dining with him on 20 September 1794.

[12] Lord Minto described a grand dinner at Montagu House, Blackheath in December 1798, given by the Princess, at which "Mrs. and Miss Lisle" were guests.

Marcia Arbuthnot died in Constantinople on 24 May 1806 in childbirth,[15] "after seven years of perfect happiness",[16] while her husband was Ambassador to the Ottoman Empire.
