1. The Adamses had been introduced to the Le Roy-Chabanel circle at Amsterdam at the very outset of their sojourn in the Netherlands. See entries for August and September in JA's Diary and Autobiography , 2:446–447. Jacob Le Roy, a native of Rotterdam, had lived for some time in New York in the mid-18th century, and his son Herman was born there. Herman translated into English the questions submitted to JA by the jurist Hendrik Calkoen that led to JA's first propaganda effort in Amsterdam, eventually published as Twenty-Six Letters, upon Interesting Subjects Respecting the Revolution in America, Written in Holland, in the Year M.DCC.LXXX, London, 1786 (JA, Corr. in the Boston Patriot , p. 194; Works, 7:265). Herman returned to America with Gillon in the South Carolina in 1781–1782, and formed successive partnerships in New York City that were long active in developing lands in western New York. The village of Le Roy in Genesee co., N.Y., was named for him. See P. J. van Winter, Het Aandeel van den Amsterdamschen aan den Opbouw van het Amerikaansche Gemeenebest, The Hague, 1927–1933, passim; John Lincklaen, Travels in the Years 1791 and 1792 in Pennsylvania, New York and Vermont, ed. Helen L. Fairchild, N.Y., 1897, p. 141–146; Paul D. Evans, The Holland Land Company (Buffalo Historical Society, Publications, vol. 28), Buffalo, 1924, passim.

JQA's diaries, kept irregularly during 1780 and 1781, show that he and CA were constantly under the care of one or another of the Le Roys and their relative, Mme. V. Chabanel, when not in school or at Leyden.
