Thanks for your offer of help. I don't know of any Shafts from Tioga Co. NY so this could be very interesting. What time period are you talking about? All the info I have on Diane/Diana Doty is in my original post. As to her husband, Dennis/Teunis Shaft, he was a son of Johannes/John and Alida Van Tassel Schaaf. There are several lines of Schaaf/Shafts who were in NY from about 1750 on. I would love to hear more about your Shafts and any connection to Dotys. Thanks.
