After the Revolutionary War, people from New England, Maryland and Pennsylvania came to settle the Genesee River Valley bringing their knowledge of agriculture and methods of raising cattle and sheep. They built flour and grist mills on the numerous small streams and on the Genesee River. The most prominent of the settlers were the Wadsworth's from Connecticut who came in 1790 to the Seneca Indian village of Big Tree, now Geneseo, the County Seat.
Growth of population came with the completion of the Genesee Valley Canal (1840-1872), with the expansion of railroads, and with health spas, which reached their height of popularity in the 1850's.
