I have scans (jpeg or gif) of 35mm prints I took at the Mt. Zion, PA cemetery sites c1988. Good coverage of Foose monuments at older grave sites and many of those located at the chirch. Also two pictures of the church. I'm in the process of finishing up this project and will share if there's any interest.
I also have a scanned version of an original copy of "History and Descendants of the Conrad Foose Family as gathered for the 3d Annual Reunion, Saturday, August 8, 1936, Mt Zion Church, Zion's Grove, PA."
There are a couple scans in my files of topo maps of the area too.
