cos1776 note: previous post indicated he was King of ??? during his life, however please note that the rulers (kings or monarchs) of the Kingdom of Prussia during this time period were all from the House of Hohenzollern, including Frederick William I of Prussia who reigned 1713-1740, so it does not appear that this person was a king of Prussia.
