Matilda received as dowry out of Ottonian possessions lands in Thuringia and Franconia (the East Frankish territories of Coburg, Salz and Orlamünde), while her husband gave her as dowry the family estate of Brauweiler.
This was finally accomplished on 24 February 1680; Frederick kept Gotha, Tenneberg, Wachsenburg, Ichtershausen, Georgenthal, Schwarzwald, Reinhardsbrunn, Volkenrode, Oberkranichfeld, Orlamünde, Altenburg and Tonna.
