Johnann Jacob Schnebele is my husband's 6ggrandfather, through his daughter Anna Schnebele who married Johannas Lang. Does this book go back from Johann Jacob? His father was Jacob Schnebele, born in Zurich Switzerland in 1624.
Just a thought: Why not send the book (or a copy of it) to the Genealogy Library at Salt Lake City. It's the largest library of its kind in the world, and the book would become available to many, many researchers.
