I've been a cemetery walker for quite a while. I was the driving force for a total restoration of the mausoleum of Major General Winfield Scott Hancock at Montgomery Cemetery in Norristown in 1994 and now run an organization based around him, the W.S. Hancock Society. You can visit us here: www.wshancocksociety.org
I come from a very old German family from Montgomery County, PA before it WAS Montgomery County and from a newer Ulster-Scot family from Conshohocken, PA.
I'm happy to help in supplying photographs of headstones as long as you can tell me where they are located in a cemetery near me.
