"Frederick, Burgrave of Dohna (4 February 1621 in Küstrin – 27 March 1688 in Lutry, near Lausanne) was a German nobleman, an officer in Dutch service and a governor of the Principality of Orange. He later also rendered services to the Electorate of Brandenburg. Near the end of his life, he chose Switzerland, where he was highly regarded, as his adopted country." - (en.wikipedia.org 16.02.2022)
