Quite a while ago I had some great luck in writing to a cemetery in the Cannonsburg-Houston area. We were told the section and block (for a small fee!!) for the gravesites we were seeking.. At a much later time, we left Pittsburgh on our way home to South Carolina, and made time to stop and look for the cemetery. With the better directions of the little office and the help of a couple maintenance people working out there, we found the location and discovered there were no tombstones. However, the cemetery was well marked in that area and there were little cement markers buried, that you really had to look for to find the block numbers. Because of the map in the office, we could tell the gravesites and how they lined up with the others. Unfortunately, it would seem for some of our other grandparents, the gravesites were not honored and were plowed under for streets, malls, and the like, particularly in Lancaster PA. I hope you all find yours... wanda casker
