Karl Anton August Schleswig Holstein Sonderburg Beck

Prince Karl Anton August of Schleswig-Holstein-Sonderburg-Beck  was the son of Peter August, Duke of Schleswig-Holstein-Sonderburg-Beck and Princess Sophie of Hesse-Philippsthal.

Marriage and issue

On 30 May 1754, Anton (as he was known) married Countess Frederica Charlotte of Dohna-Schlodien in Leistenau (3 July 1738 – 21 April 1785) in Königsberg. The couple had one child, Friedrich Karl Ludwig, Duke of Schleswig-Holstein-Sonderburg-Beck (20 August 1757 – 24 April 1816).

Anton would have inherited the dukedom of Schleswig-Holstein-Sonderburg-Beck had it not been for his early death by wounds suffered at the Battle of Kunersdorf.

 His father Peter outlived him, so the dukedom was passed on from Peter to Anton's only son, Friedrich.
