Although his father was Elector of Hesse until the electorate was abolished in 1866 (after which he was exiled to Austria),[2] upon his father's death in 1875, Friedrich Wilhelm and his younger brothers were all excluded from the line of succession due to his parent's morganatic marriage. Therefore, his uncle, Prince Frederick William of Hesse-Kassel, succeeded as titular Elector of Hesse and the Head of the House of Hesse-Kassel.
At their birth, his sons were Counts von Schaumburg, but post-1918, his descendants bear the title Prince and Princess von Hanau.[3]

They eloped to London where they were married on 23 September 1856 and she became Countess von Schaumburg. Because of his threats, her father was imprisoned and her family exiled and persecuted.
