DePeyster is a town in St. Lawrence County, New York, United States. The population was 998 at the 2010 census. The name is taken from that of one of the land owners of the region, Frederic de Peyster,[2] grandfather of John Watts de Peyster.
The town was first settled around 1802.
The town was established in 1825 from parts of the Towns of DeKalb and Oswegatchie. The town name was proposed to be "Stilwell" after prominent resident Smith Stilwell, but he declined on the grounds that "some one among the proprietors, might be willing to make the town a liberal present, for the privilege of giving it their name". Thus, a correspondence was opened with landowner Frederic de Peyster, whose name was ultimately chosen for the new town.[3]
Newton Martin Curtis, Medal of Honor recipient - born in the town and was a postmaster, brigadier general, and customs inspector.
Patty Ritchie, New York State Senator - raised in DePeyster.
