There does not seem to be a cemetery in La Rochette, Savoie (73) - (odd!) - see:http://www.pagesjaunes.fr/annuaire/la-rochette-73/cimetieres
which will refer you to 6 cemeteries nearby, one of which is in Chambery.
Here is another site for cemeteries in Chambery (73) Savoie - two cemeteries:http://association.118000.fr/v_chambery_73/c_cimetiere
