I know of an Erastus Colf who is buried in the Bellows Corners Cemetary in Ashford, NY. He also has a daughter, Frances, buried there as well. I am descended from Erastus' brother Gehial Colf. I didn't know where the Colf's came to Ashford from, do you know the town in Monroe co.? Please e-mail me for more information. Thank you.
