Painted for the sitter's father, Sir Christopher Willoughby, Bt. [1748-1808], Baldon House, Oxfordshire; by descent to Sir John Willoughby, 5th Bt.,[1] Fulmer Hall, Slough, Buckinghamshire; sold 1906 to (M. Knoedler & Co., London and New York); purchased February 1907 by Andrew W. Mellon, Pittsburgh and Washington, D.C.; deeded 28 December 1934 to The A.W. Mellon Educational and Charitable Trust, Pittsburgh; gift 1937 to NGA. [1] The 2nd through 4th Baronets Willoughby added to the former owner table in the NGA collection database are per The Getty Provenance Index, which lists these baronets each with the symbol (?), indicating some doubt as to the painting's direct passage through these three succeeding brothers down to the 5th Bt.
