Update: Maria translated the article that talks about the podcast:
During the talk show "Leute" ("People") at German radio station SWR1, which aired on Sunday 25th of July 2010, David found out for the first time that his family original came from place called Völkersen positioned around 30 km from Bremen.He was very surprised and touched by this information and immediately asked are there still some Hasselhoffs living in Völkersen and said how he'll for sure go and search for his "new" family.Professor Jürgen Udolph, well known expert in the field of genealogy from the Leipzig University and by the order of SWR1 radio station, has been able to track David's ancestors all the way to 16th century. It seems that the farm was in the near of hazelnut tree (Haselnussstrauches in German). Udolph has also said that the house and the farm should still be existing in Völkersen, 30km south of Bremen. Until this moment, David thought that his family is coming from Nordhessen near Kassel because there's a place called Hasselhof.Show moderator Birgit Steinbusch gave David copies of the documents that professor Udolph has found and they included signatures of family members for population census, a draft of notice from the First World War and even the passenger list from the ship that brought David's great-great-grandmother Meta Hasselhoff and her family to Baltimore in 1865."This is the greatest and the most important gift I've ever got" said excited David and finished with: "I love Bremen!"

David will be in Stuttgart, Germany on July 13 to autograph and promote his book at Hugendubel Bookstore on Königstrasse, near the main station. He will be there at 4 p.m., so don't be late!
