Prince Arsen of Yugoslavia

Prince Arsenije "Arsen" of Yugoslavia (16/17 April 1859 – 19 October 1938) was a dynast of the House of Karađorđević and ancestor of the current cadet branch of the Royal Family which ruled Yugoslavia until 1945. He served as an officer in the Russian Army.

Their son was Prince Paul of Yugoslavia who was Regent of Yugoslavia from 9 October 1934 to 27 March 1941. The couple divorced on 26 December 1896 and Aurora Pavlovna was remarried to Count Nicola Noghera in Genoa on 4 November 1897, with whom she had a daughter, Helena Aurora di Noghera (22 May 1898 – 12 October 1967).
