Davies was born at the Château of Saint Germain to Marie Elizabeth Luce de Longuemarre (died 1824) and Lord Leon Maurice Drummond de Melfort (1761–1826), the fourth son of James Drummond, 3rd Duke of Melfort in France. Her father"s elder brother would have been thirteenth earl of Perth but for the attainder of his ancestor.
Her brother George"s claim to be heir male of the Earls of Perth was admitted by the House of Lords in 1848, and the attainder was reversed in his favour on 28 June 1853, and she herself was granted a patent of precedence as an earl"s daughter on 30 September 1853.
She saw a great deal of life, and at times suffered some hardships. Her husband died at Koblenz on the Rhine on 22 October 1863, aged 72.
