The 7th Earl left 20,000 to Mr Charles O'Brien and the family estates to his wife's nephew, Percy Wyndham later Wyndham-O'Brien, who in 1756 was created Earl of Thomond. This new Earldom became extinct on his death in 1774.

 

On the death of Mr O'Brien's only son and heir, Charles, also in 1774, the male issue of Donogh [O'Brien], 2nd and 1st Earl of Thomond, became extinct and the representation of the House of O'Brien passed to the Barons Inchiquin.
