Thomas, Jeremiah, and Jacob, who appear to be relatives (brothers or sons), appears in tax documents for the area that became Greene County beginning in 1787. According to deeds located in the Greene County Clerk's office, Silas bought and sold numerous parcels of land in the late 18th century and early 19th century. The Rushmores also owned a grist mill, originally known as the Van Vechten Mill, in the town of Catskill, on the Catskill Creek. A Quaker marriage record from the Nine Partners Monthly Meeting, Dutchess, N.Y. for Thomas Rushmore, son of Silas and Phebe, to Abigail Griffin in 1797 suggests that the Rushmore family was living in the Hudson Valley by this date. 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
