Painted for the sitter, the Hon. Sir Francis Nathaniel Pierpont Burton Conyngham [1766-1832], County Clare [Ireland]; by descent to his grandson William Conyngham Vandeleur Burton [1846-1919], Carrigaholt Castle, County Clare; from whose estate it was sold to (Tooth Brothers), London, from whom it was purchased 16 March 1920 by (G.S. Sedgwick) for Thomas B. Clarke [1848-1931], New York, as by Gilbert Stuart; sold by Clarke's executors to (M. Knoedler & Co., New York), from whom it was purchased 29 January 1936, as part of the Clarke collection, by The A.W. Mellon Educational and Charitable Trust, Pittsburgh; gift to NGA, 1947.
 Clarke's purchase from Tooth is according to 1928 Clarke exhibition catalogue annotated with information from files of M. Knoedler & Co., NY (copy in NGA curatorial records and in NGA library). The painting probably passed through William Burton's father, Henry Stuart Burton [d. 1867], and perhaps also through the latter's eldest son, William's older brother Francis Nathaniel Valentine Burton [d. 1883]. See Burke's Peerage, Limited, Burke's Peerage and Baronetage, 105th ed. (London, 1970), 627.

The canvas is plain woven; it is unlined. The proprietary white ground is of moderate thickness. The composition is oval in format; the area outside the oval is painted in brown. The painting is executed in thin, fluid, opaque layers, blended wet into wet, with slight impasto in the reds and whites; the shading in the blue coat and the delineation of the feigned oval are accomplished with a gray glaze. There are pentimenti in the red collar, which has been shifted in position. The painting is in excellent condition. There is little loss or abrasion, and no areas of retouching. The natural resin varnish has not discolored.
