Locke was well known as a wealthy amateur of his day, and formed a collection of works of art at Rome, which included the picture of 'St.

Ursula' by Claude, now in the National Gallery, and among other antique marbles the 'Discobolos,' afterwards at Duncombe Park, and the torso of Venus, which, was in the Duke of Richmond's collection, and after injury by fire came to the British Museum.

In 1774 he purchased an estate at Norbury, near Mickleham in Surrey, where he built a house, one of the rooms in which was decorated with paintings by G. Barret, Cipriani, and other artists.

de Stael and others, settled at Juniper Hall, near Norbury, they were very intimate with the Lockes, who materially assisted the marriage of M. d'Arblay and Miss Burney.

By his wife, Frederica Augusta, he left among other children two sons, William (see below) and George, and a daughter Amelia, married to John Angerstein, M.P., of Weeting, Norfolk.

Locke painted several historical and allegorical subjects in a strained and affected style; one, 'The Last Moments of Cardinal Wolsey,' was engraved in stipple by Charles Knight.
