Just found your query, and wondered if you ever saw the Tinstman/Tintsman chapter in ALONG THE BANKS OF JACOBS CREEK, by Winifred Erb Paul? There is quite a lot of material. Also, Adam Tinsman is mentioned in the book, DEEP RUN MENNONITE CHURCH EAST: A 250 YEAR PILGRIMAGE, 1746-1996.
Also, members of the Tinstman family are in the Oberholtzer/Overholt family tree. See them in "A Genealogical Record of the Descendants of Martin Oberholtzer," by Rev. A. J. Fretz, and THE OBERHOLTZER BOOK, by Barbara B. Ford, and are mentioned in articles on my web site. If you need more information on these resources, please write. My e-mail address is at the bottom of my Table of Contents.
Bye, for now! K. R. Overholt Critchfield
