The cemetery in Bissingen has one "Joachim" gravesite currently, that of Josef, Josefa, Sebastian, Kaspar, and Peter Joachim, and Crescentia and Anton Schäferling. There are a number of gravesites that could be Joachim descendants, at the time of developing this website this information is not available.
In Germany, a cemetery plot is purchased for a certain number of years. It is maintained by the family/owner. If the lot fee is not renewed, the plot is re-used. The stone may or may not remain within the cemetery.
