Early life
Demidova was the eldest daughter of Pavel Pavlovich Demidov, 2nd Prince of San Donato, and his second wife, Princess Elena Petrovna Trubetskoy (1853–1917). Her paternal grandparents were the Finland Swede philanthropist Aurora Stjernvall von Waleen (later Karamzin) and Russian Pavel Nikolaievich Demidov. Her maternal grandparents were Prince Peter Nikitich Trubetskoy (1826–1880) and Princess Elizabeth Belosselsky-Belozersky.
First marriage
Demidova married Prince Arsen of Serbia, youngest son of Alexander Karađorđević, Prince of Serbia and Princess Persida, at the Uspenski Cathedral in Helsinki (where her grandmother Aurora lived) on 1 May 1892. Their son, Prince Paul of Yugoslavia, who later became the Regent of Yugoslavia, was born the following year. They divorced in 1896 due to Demidova's affair with Count Ernst Andreas von Manteuffel (1873–1953), elder son of Count Ernst Gotthard II von Manteuffel (1844-1922) and his wife, Marie Dorothea von Weiss (1847-1938), which led to the birth of twins, Nikolai (1895–1933) and Sergei (1895–1912). Nikolai is buried next to his mother in the Russian Orthodox Cemetery, Nice.
