Hi! It´s been more than a year since you posted your question about cemeteries in the Zeltingen area, better late than never, I suppose- here´s another reply! We spent a week there recently, and, though not searching for any cemeteries, we almost stumbled across one, in the hills above the villages. http://www.panoramio.com/photo/1384509
shows a picture from the site. It is almost certainely jewish, and no longer in "use". I saw graves with burial-dates in the 1920´s.
