After a brief "European preface," the book identifies Ulrich's descendants, locates their lands in the Northkills, Somerset Co., Pa., and Tuscarawas Co., Ohio, Amish communities to ca1850. It names scores of other Amish-Mennonite families in those communities. It emphasizes the detailed location, citation, and analysis of all primary (and other) documentation and reproduces many public primary documents. This is a revised reprint of the original 2008 edition. (258pp. illus. index. Masthof Press, 2023.)
