Jessy, what makes you think your Reuben is son of William and was briefly in Plainfield, Otsego Co, NY? The Reuben Wilcox of Plainfield, Otsego Co, NY is son of Ephraim Wilcox of Plainfield. I have a copy of Ephraim's will. I believe this is the same Reuben Wilcox who married Sara Clark and is buried in Brookfield, Madison Co. This Wilcox family had property in Plainfield and Brookfield, the Clark family lived next door in Plainfield. Sharon
