Daytonville is an apparently uncommon old nickname for a part of the Village of Lansingburgh. It appears to have referred to land owned by Stephen S. Dayton from 680 First Avenue to 2 119th Street, which was south of Edward Tracy’s malt houses.

In the days we refer to, the strip of ground on River street [First Avenue], north of Daytonville, at present owned by Edward Tracy, was used as a buryal [sic] place, and a few years since, more than a bushel of bones of these early settlers were exhumed, together with a large quantity of silver coin, that probably had been buried for a hundred years.
