She was born at Stourhead, Wiltshire, the daughter of wealthy banker Henry Hoare and his second wife Sarah, formerly Sarah Colt. Her elder sister, Anne, married Sir Richard Hoare, 1st Bt., and died in 1759.
Viscount Dungarvan died in 1759. The widowed Lady Dungarvan married Brudenell-Bruce on 17 February 1761 at Tottenham Park, Wiltshire.[5] Their children were:
Lady Caroline Anne Brudenell-Bruce (d. 1824), who died unmarried
George Brudenell-Bruce, Lord Bruce (1762–1783), who as a child was painted by William Hoare, died unmarried
Lady Frances Elizabeth Brudenell-Bruce (1765–1836), who as a child was painted by William Hoare, married Sir Henry Wilson; the couple later took the surname Wright to secure an inheritance[6]
The countess died in 1783, aged 50. She was an artist in needlework whose “piece of flowers in needle-work” was considered sufficiently of interest to be exhibited publicly in 1768 by the Free Society of Artists, as was subsequently catalogued[7] by the publisher and art historian Algernon Graves. The portrait of her by William Hoare shows her holding yarn and she appears to be engaged in lace tatting. Her dress carries prominent black lace tatting decorations.
Five years after his first wife's death, the earl married Lady Anne Elizabeth Rawdon (1753–1813); they had no children. The earl himself died in 1814.
