(1) According to Kleinberger. Michael Robinson says there is no evidence for this.

(2) The musician Frederic Wilhelm Michael Kalkbrenner also owned Jacob van Ruisdael’s Extensive Landscape with a Ruined Castle and a Village Church (private collection, New York), Slive 2001a, no. 56. An estate sale of Frederic Kalkbrenner’s collection of thirty old master paintings was held in Paris by Laneuville on 14 January 1850.

(3) According to M. Robinson 1990, vol. 1, p. 364, referring to Smith 1829–42. The sale is unrecorded.

(4) The entry for the painting in the 1958 sale catalogue incorrectly states that the painting was "From the Collection of Joseph Bernhard," rather than Joseph Barchard. According to an annotation made by Ellis K. Waterhouse on p. 16 of the Getty Research Institute’s copy of the 2 July 1958 sale, "Mainly bt. by Joseph Barchard, a client of Nieuwenhuys at the beginning of the 19^th century. He bequeathed them to Francis Barchard, thence to Elphinstone Barchard, great uncle of [?] Francis Barchard whose widow is the vendor [Mrs. Maud Barchard]. (He died ca. 1932.)" It was apparently the elder Francis Barchard who lent the painting to the Royal Academy of Arts, London, in 1875. According to Mireur 1911–12 (2001), vol. 7, p. 312, in 1828 (sale not identifiable) J[oseph] Barchard sold another painting, Un calme, which had been in the sale of the duc de Choiseul in 1772 and described by Mireur, p. 311, as "Un calme. Vers la droite, un vaisseau navigue sous des oiles de misaine et de hune; une barque est a gauche et plus loin, au fond, on apercoit deux fregates, un sloop et quelques batiments. Bois (23.6 × 27.9)."

(5) The painting and property may have first passed to Elphinstone Barchard’s son Edmund Elphinstone Barchard (1874–1915), who died on the RMS Lusitania in 1915. Edmund was a British citizen who was living in Columbus, Ohio, with his wife at the time of his death.

(6) Her only son, Lt. Cmdr. Francis Barchard, died in action during World War II, 25 November 1941.
