From British Newspaper Archive: Newcastle Courant Saturday, 19 April 1777 Page 4 Newcastle

Yesterday night, at his seat at Etal in Northumberland, in the 78th year of his age. Sir William Carr, Baronet. A fine person, affability, and polite behaviour, with every other accomplishment that distinguishes the gentleman composed his character. Sir William married one of the Miss Bacon's of Newton Cap, by whom he had two daughters; the eldest married the Right Hon. the Earl of Erroll, to whose second son he has left his estate; and the second daughter to General Mackay, to whom has left considerable fortune. By his second lady, the widow of Henry Ogle, of Cawsey Park, Esq; he had no issue. The title descends to his brother Robert Carr, of London, Esq.
