In this fourth episode of Series Six, host Andrew meets family historian Sven Grewel, who has been tracing his German ancestry for many years and has since become a professional genealogist. He explains how he got hooked on researching his family history, and the challenges of researching in Germany - a country that has frequently changed its borders through history. THE LIFE STORY - JOHANN CARL MAX SABEL Sven has chosen to tell the life story of his 2x Great Grandfather Johan Carl Max Sabel who worked as a policeman in between the First and Second World Wars. This was a dangerous time, and unfortunately whilst delivering justice as a policeman, he is accused of a crime. He spends years fighting for his innocence against a backdrop of rising Nazism, which includes time in prison and a psychiatric clinic, as his crime gets bigger and evidence seems lacking. Something doesn't seem right! THE BRICK WALL - KARLSTADT RECORDS A puzzle in Karlstadt, Bavaria, Germany is causing Sven a headache, so it's time for us to try to help. Sven's research has been troubled by the destruction and burning of records that took place during The 30 Years' War that spread across what is mostly now Germany between 1618 and 1648. For many of his family branches, this is war causes his research to hit a dead end. One place in particular he would like to find records is the town of Karlstadt in Bavaria, but the records are either lost, mislaid, or destroyed. Sven is feeling lucky though, and hopes that a listener might just be able to help find some. If you think that you can offer Sven some help, then you can reach out to him directly at his website svengrewel.com. Alternatively, you can send us a message and we'll pass it straight on to him. In the meantime, Sven jumps at Andrew's offer of help but will he get the information he's hoping for?  - - - Episode Credits: Andrew Martin - Host and ProducerSven Grewel - GuestJohn Spike - Sándor Petőfi Thank you for listening!
