2 options: Witzin is approx 5 miles south of Boitin, the parish of Grunenhagen. This is about 15 miles SE of Gustrow, Mech-Schwerin. Wotenitz is 15 miles west of Wismar in the parish of Grevesmuhlen. distance from Wotenitz to Boitin is about 25 miles. I would check the parish records for Witzin (it is the parish and town), and also Grevesmuhlen, if you are looking for his birth. But I have found that the towns listed on marriage records from that area are the towns of RESIDENCE at the time of the event, NOT THE BIRTHPLACE. If you would like to see a map of either place, let me know. Both show on the AutoRoute Express program.
