I have a copy of "The Stauffer Book". I'm not sure this is what you are looking for, but it is a copy and not a very good copy. This book was printed in 1911 and was compiled in honor of the 200th anniversary of the landing of the Stauffers in America.
My Grandmother was Marion & did live in Connecticut.
There is actually a portion of the book that is in German, which I had tranlated a few years ago.It was a speech made during a reunion and an unveiling of the monument of John Stauffer and his wife in the cemetery of St. Peters' Church in Pennsylvania.
I don't know where you could get a printed book.If you think you may have something different - I would be interested in knowing if there is another book.
I would also like to update my book with any information you may have, as mine ends with a partial list of the children of Horace Stauffer.
