The location of my Great Grandparents (parents of my father's mother) was identified in the Manuscript. The address was Bahnhofstr 4.
At the time, Sonneberg was a centre for the production of toys and Christmas ornaments. For those who ran such a business, common practice was to have a factory (for production) and residence connected. My great grandparents owned and operated a factory producing teddybears and Christmas ornaments, and like the usual practice, their facility included both a residence and a factory.
The front part of the building contained the residence; the rear, the factory. The tudor-styled structure was the factory.
