I would like to determine the history of early saw and grist mills in the Helderbergs of western Albany County. I suspect that the earliest grist mill was on Fox Creek in Beaver Dam, now Berne, and was built about 1774 by Jacob Weidman. I presume a saw mill had to have been constructed beforehand for lumber to build the grist mill. It was probably built above or below the grist mill. Any information or suggested sources on early mills would be much appreciated. Hal Miller
