She was the daughter of the Honorary Robert Boyle, later Boyle-Walsingham (1736–1780) and wife (m 1759) Charlotte Hanbury Williams (d 1790), daughter of Sir Charles Hanbury Williams and Lady Frances Coningsby.
After petitioning King George III in 1790, she eventually (in 1806) established her entitlement to the Barony of de Ros, the most ancient baronial title in England, legally changing her name by Royal Licence on 6 October of the same year to Charlotte Fitzgerald-de Ros. They had links with the brightest of society, from the Duke of Wellington downwards. Henry"s younger brother was the notorious Lord Edward Fitzgerald.

In London on 3/4 August 1791, more than a year after her mother"s death, Charlotte married Lord Henry Fitzgerald, a member of the Duke of Leinster"s family. Members of the de Ros family lived in Thames Ditton for a long while.
