Susanna Brudenell-Bruce, Countess of Ailesbury

Her first husband was Charles Boyle, Viscount Dungarvan, whom she married in 1753; the marriage was rumoured to be unhappy.

The widowed Lady Dungarvan married Brudenell-Bruce on 17 February 1761 at Tottenham Park, Wiltshire.

The portrait of her by William Hoare shows her holding yarn and she appears to be engaged in lace tatting.

Five years after his first wife's death, the earl married Lady Anne Elizabeth Rawdon (1753–1813); they had no children.

A portrait of the countess, dated 1757, by Arthur Pond, is held by the National Trust at Stourhead.
