Selah, b. ca. 1770, prob. Ulster Co., NY
I have a book "Early Architecture in Ulster County (NY) because many of my ancestor lived there (VanMeter, DuBois, etc.)
"Grist Mill, Tuthilltown - Build in 1788 by Selah Tuthill when he was 18, this is the only known mill which has remained in almost continuous operation since its beginning."
ther is a little further information about the mill and there are two black and white photographs.
