married when she was 15! They would have 2 children.
This marriage really became unhappy, due to Ulrich's violence. Finally
Sabina was forced to flee from Württemberg. She left her children behind
and found shelter by her two brothers in Munich.

to Nürtingen. This was the official widow's residence of the Württembergs.
