Genesee County New York History
It was not until the Holland Purchase of 1793 that Western New York was officially enforced as the territory of New York State. Land in the region was sold through the Holland Land Company's office in Batavia, starting in 1801. All of the land in Western New York was in the newly created Genesee County, and all of that was in the single town of Batavia.
Genesee County was created by a partition of 7,100 square miles (18,000 km2) of land from Ontario County. The County was not fully organized so it remained under the supervision of Ontario County until it achieved full organization and separation during March 1803.
April 7, 1806, Genesee’s area was reduced to 5,550 square miles (14,400 km2) due to a partition that created Allegany County. On March 8, 1808, Genesee’s area was again reduced, this time to 1,650 square miles (4,300 km2) due to a partition that created Cattaraugus, Chautauqua, and Niagara Counties. On February 23, 1821, Genesee’s area was again reduced, this time to 1,450 square miles (3,800 km2) due a complex partition that produced Livingston and Monroe Counties. On April 15, 1825, another partition reduced Genesee’s area to 1,030 square miles (2,700 km2) in the creation of Orleans County. On May 1, 1826, the Orleans partition was again surveyed, with 10 square miles (26 km2) of land along the western half of the Orleans/Genesee border returned to Genesee. On March 19, 1841, Genesee’s area was again reduced, this time to the 500 square miles (1,300 km2) it remains to this day due to the partitioning to create Wyoming County.
