Son of Everard Fawkener (1684-1758) and Harriet Churchill (ca. 1726-1777).1 In 1774 he married Georgiana Ann Poyntz (1763-1851), but the marriage soon ended in divorce, and his then former wife married Lord John Townsend in 1787. He then married Elizabeth Wright, with whom he had two daughters.
A clerk to the Privy Council, he was in 1791 sent on a secret mission to Empress Catherine II of Russia.2
Boswell rode with Fawkener, then a student at the Collegium Carolinum in Brunswick, from Brunswick to Wolfenbuttel on August 14, 1764. He described him as a genteel, pretty, amiable young fellow
