The area that is now Williamson Town was first settled by Daniel Russell about 1794. The town is perhaps most noted for the Lake Ontario port hamlet of Pultneyville. Prior to the opening of the Erie Canal, Pultneyville was a U.S. Port of Entry serving towns as far south as Canandaigua. Pultneyville, together with Palmyra and Canandaigua formed an active branch of the underground railroad.
"From the home of Griffith Cooper, the slaves were sent to Pultneyville to the home of Samuel Cuyler, until such time as they could be transported to Canada by ship. One of the captains who transported slaves was Capt. Horatio N. Throop. My Cuyler would, invariably say to Capt. Throop, "Capt. Throop, I have some passengers for you." Capt. Throop would always reply, "My boat runs for passengers." — Williamson Town Historian.
