Although burial sites have some importance and I have checked for later ones, I have, when visiting ancestral sites in France, Germany and England, found going to their churches and looking at the baptismal fonts (if dating from the right times) more meaningful. Sometimes, but not frequently, their houses also. I was able to see houses in Niederroedern, alsace through the help of a local knowledgable person. Twice we stayed at the very old Gasthaus of other ancestors in Germany. That was thrilling. (No one was at home, however). I was invited in to two in England. Not always possible but extensive research and even google earth are helpful. Gloria Ishida "Genealogy. An account of one's descent from an ancestor who did not particularly care to trace his own."
