I was down to the Ft. Loudon Cemeteries last weekend. The one cemetery is in very poor condition. About 60% of the stones cannot be read. and allot of stones are broken off. I could not find your Mowrey. I also looked in cemetery books in the Historial Society in Chambersburg and did not seem him listed, The books were written in the 1980's, so his stone may be gone by now. In the book-- FORT LOUDON SIDELIGHTS written by Harry F. Foreman, 1970, on page 28 in states Mowra (Mowery) The John Mowra land was connected with the James Smith land. Jacob Mower sold some of the land to John Beaver. Judy
