A postscript for this discussion: My great-grandfather was buried in Glenwood, along with other family. They are now in Riverside Cemetery in Norristown, PA. The records at Riverside indicate that the grave site there was purchased by Glenwood in 1917. I can only speculate as to the process, but, clearly, somehow my family -- who was living in Norristown/Bridgeport in 1917 -- was able to get these graves out to a location near their home, apparently with the assistance of Glenwood Cemetery.
