I don't have any genealogical information but remember my grandparents John & Mary Gerger visiting the Tapler family in the Gussing area in the 1970s. (My great grandmother Rosalia Rokker Gerger was born in Tobaj). I don't think there is a family connection but the families were good friends. I can look for the pictures but recall there are a few with several generations of the family, including some who were children at the time. But there might be some still living in that vicinity. Check the Burgenland Bunch to see if anyone can help. Good luck!
