daughter Sophie Louise married Frederick (1638-1684), son of Otto, Count of Lippe-Brake. His other daughter Dorothea Amalia married Count Philipp Ernest (1659–1753), son of Philip I, Count of Schaumburg-Lippe. Legacy August Philipp founded the ducal line of Schleswig-Holstein-Sonderburg-Beck. His sons and their descendance went into Prussian, Polish and Russian service until his grandson's great-grandson took over Glücksburg Castle and the line changed its name to Schleswig-Holstein-Sonderburg-Glücksburg in 1825. August Philip is thus a male-line ancestor of the British, Danish, Greek and Norwegian royal families.
