I am planning a trip to Bavaria (Cham district) and am planning to visit the Bischöflisches Zentralarchiv in Regensburg, but will also be touring the region (from Reichenbach, to Falkenstein, to Köthmühl to Arrach) along with the various zells and small villages surrounding. I was wondering how far back I am likely to find existing tombstones in cemeteries in the region as I have my direct line back to the mid-1700's, but know the line goes back much further.
