Richard (1773-1845) and Catherine Garnons (d.1853/54) were children of Richard Garnons, brother of Catherine Jones [P216] of Colomendy Hall, Loggerheads, Llanferres, Mold, Denbighshire, a cousin of Wilson. Catherine Garnons was left Colomendy Hall, and came to live there with her brother Richard. Wilson had spent his last year there before his death in 1782, when it was the home of her godmother, Catherine Jones (1701-1786). Thomas Wright [of Upton], Wilson's biographer, visited Colomendy Hall some time before 1824 and stated that he saw there 'several of Wilson's pictures in an unfinished state, with two or three merely in dead colour'. He mentioned the subjects of two and added 'These pictures were brought by Wilson, upon his retiring from London'. In 1854 the Garnons bequeathed numerous Wilson works to the National Gallery, London. These have since been transferred to Tate, London and include:
P1 Ascribed to Wilson, View of Carlton House, with a Royal Party in the Grounds;
P24B George III and the Duke of York;
P28 A View on the Thames;
P123 Lake Avernus - II;
P155 View near the Loggerheads, Denbighshire (A Welsh Valley with a Quarry);
P178A The Falls of Niagara;
Valley with a Bridge over a River (not illustrated in Richard Wilson Online)
