With the Lynden family you mean the Dutch countly family of that name? I do not believe there is a German one. The head of the family would be count Frederik van Lynden van Sandenburg, who resides at Sandenburg Castle in the province of Utrecht. He married firstly a Jkvr. Roëll, which ended in divorce. He secondly married Anne Louise Metz, from New York, who works at the Amsterdam stock exchange. The Dutch Crown Prince attended the wedding in NYC in 1999 and met his future with for the second time during this trip.
I believe that the head of the Belgian side branch is count François d'Aspremont Lynden, who is married to baroness Régine del Marmol. This part of the family was incorporated in the nobility of the Holy Roman Empire, so perhaps that is what you are looking for.
