The story

How Yaphank came to be

From Wikipedia’s history of Yaphank.

Captain Robert Robinson came to Yaphank and built his Dutch Colonial house with the building dated at 1726. He was then granted permission to dam the Carmans River to build a mill across the street from his house. The construction of this mill in 1739 was considered the founding date of the Hamlet of Yaphank.
