Jonathan Middaugh is my GGgrandfather. His daughter Jane married David Heater in Jan 1860 in Matamoras, PA. Until I saw your posting I only had the first name of Jonathan's wife. I have been in contact with William Heater, who is also a GGgrandson of Jonathan and he has given me much information about the Heaters, Middaughs, and many other old families in the PA/NJ/NY area. The information in your post is very close to the information I have so I believe we are talking about the same family. I do not have Mary Letitia as a child of Jonathan and Sarah, but I do have Benjamin B., b. abt 1844 Pennsylvania listed as a child. I would love to compare notes. Please contact me.
