I slipped out of the office and got a limited amount of time at the Archives.Unfortunately, Jeremiah Dodge died one year before the Westchester probate records begin. Prior to that, they were handled in Manhattan. I know from prior experience that probate files for this period do not exist in Manhattan either. The NYC Archives may have a probate inventory but, if one exists, it is unlikely to be very helpfull.
I looked at the genealogy files and cemetary indexes for the Sutton, Underhill and Dodge families. I didn't learn much except another connection point: It appears that Mary, the daughter of Joseph Sutton and Mary Sands, married Tristram Dodge. Perhaps you already knew that but I didn't have it on my chart.
I did get a pedigree chart entitled "Pedigree of Underhill of Westchester" which I thought might be helpfull.I will e-mail that to you tonight. They had an eight volume work on the Underhills put out by the Underhill Society. I didn't have time to fully explore this but it does confirm that many of the Underhills in Westchester were quakers.
That's all for now. I still have some leads to pursue in the city the next time I go in. Let me know if you have ideas of what I should check at the Westchester Archives. I didn't yet look (for lack of time) at their Harrison genealogy file (if they have one).
