silas rushmore's son jeremiah was born in hempstead, long island in 1765. he married martha roby and they had three children: richard (1787–1837), anna (b. 1804) and morris (b. c1814). between 1790 and 1799, census records list both silas and jeremiah rushmore as heads of households with land in athens; however, it is unclear which of them purchased the nominated property. jeremiah rushmore is the probable builder and first documented occupant of the nominated house. tax records from 1799 show that jeremiah rushmore owned a house and land in the town of catskill (athens was not a separate town until 1805) valued at 1,560 pounds and personal wealth of 172 pounds. the 1801 tax assessment also lists jeremiah as owning a house and lands in catskill with a personal estate value of 3,000 pounds. an article in the catskill recorder reporting the death of one of jeremiah rushmore's workers in september 1806 documents his ownership of the nominated house by that date. although another article reported that the house and two hundred acres of land, including one hundred acres of meadow, were for sale in 1811, jeremiah purchased an additional in 1812 and retained ownership until his death, when the property passed to his son richard in 1813, another article described the rushmore property as including three orchards with over three hundred trees. jeremiah rushmore died 28 october 1828. his will and codicil, dated 1826 and 1828, respectively, and probated in november 1828, stipulated that his son morris was to inherit the farm he was living on in coxsackie and that richard would inherit the athens farm. the will confirms that the second half of the house had been constructed before jeremiah's death, in that it specified that his wife, martha, and unmarried daughter, anna, could continue to live in his "new house" and use the upper (first floor) room and two bedrooms upstairs. in the codicil rushmore specified that his daughter was not permitted to enter the old house. martha rushmore was permitted to use the franklin stove in the upper room and richard was directed to provide firewood for martha and anna. jeremiah was very wealthy, and at his death an inventory of his possessions showed that he had almost $300 along with forty-one linen sheets. his widow, martha, died on 21 february 1830. richard rushmore married deborah wilson (date unknown) and the couple had nine children: thomas lembuck (b. 1810), delanco (no dates), mary e. (1815–1865), solon (1816–1870), infant son (1817–1821), james (1818–1821), erasmus (1823–1886), martha ann (1828–1831), and laban coleman (1830–1909). after her husband's death on 3 january 1837, deborah and her minor children continued to operate the farm. the new york state agricultural census for 1855 reported that the farm consisted of two hundred acres, produced five hundred pounds of butter, and had apple orchards. the rushmore property appears on local maps in 1856 and 1867. there was also a cider mill located on the property at this time, and the family continued to own and operate the catskill mill.
