Arriving Stuttgart Aug 31, 2012, renting a car to tour Southern Germany, trying to locate a Catholic church and orphanage that would have been in operation mid 1800's in the area of Geislinger and surrounding countryside. What is the best way to drive there and do we need to make reservations in advance for accomodations? My great grandfather was Reinhold Stehle, a vinegar maker, and my great grandmother was Agnes Haug. We are trying to find any family records. Thank you for any help.
