, ca. 1810 . In 1789, Armstrong married Alida Livingston (1761–1822), the youngest child of Judge
Robert Livingston (1718–1775) and Margaret (
née Beekman) Livingston. Alida was also the sister of Chancellor
Robert R. Livingston and
Edward Livingston. Together they had seven children: • Maj
Horatio Gates Armstrong (1790–1858), soldier in the War of 1812. • Henry Beekman Armstrong (1791–1854), also a soldier in the War of 1812. • John Armstrong (1794–1852), who moved to
New York and took up life as a gentleman farmer at
La Bergerie, a farm purchased from Alida's family in
Dutchess County • Robert Livingston Armstrong (1797–1834) • Margaret Rebecca Armstrong (1800–1872), who married
William Backhouse Astor Sr. (1792–1875) of the prominent
Astor family.
Residences Almont Armstrong's initial farm in Dutchess County, called "Altmont" (also known as "The Meadows"), was originally part of the Schuyler patent. In 1795, he purchased a part of the farm from the Van Benthuysen family, and converted an existing barn into a two-story Federal style dwelling with twelve rooms. Around 1800, Armstrong sold "Almont" to
Andrew and Anna Verplanck Deveaux. Deveaux died in 1812; in 1816 his widow sold "Deveaux Park" to
John Stevens. The mansion burned down around 1879. In 1908, lumber rights to the white oak and chestnut forests were sold for timber for the New York market.
La Bergerie After the death of Margaret Beekman Livingston, widow of Judge Robert Livingston, much of the Clermont land was distributed among the heirs. John R. Livingston received the land that would become the "Messena" estate. His sister Alida Livingston Armstrong inherited the property just to the south. There the Armstrong's created "La Bergerie", in English "the sheepfold" – an estate where they raised Merino sheep. The Merino sheep were a gift from the French Emperor
Napoleon Bonaparte on Armstrong's departure after being Minister. The Astors purchased it for a summer home and renamed it
Rokeby.
Margaret Chanler Aldrich, great-granddaughter of Margaret Armstrong Astor, married
Richard Aldrich. Rokeby remains in the Aldrich family. ==See also==
