Career
She died two days after giving birth to a son, Elim Pavlovich Demidov, 3rd Prince of San Donato, at Hietzing in the suburbs of Vienna on 6 August 1868. Her loss had a lasting effect on Pavel, who remained inconsolable for a long time, spending a long while in the room in the Villa San Donato where his wife"s dresses were kept to try to recover her presence. In Saint St. Petersburg on 2 June 1871 he remarried to Princess Elena Petrovna Trubetskaya (Saint St. Petersburg, 25 September 1853 - Odessa, 28 July 1917), with whom he had six children:
Prince and Count Nikita Pavlovich Demidov (17 March 1872 - 25 March 1874)
Princess and Countess Aurora Pavlovna Demidova (Kiev, 2 November 1873 - Bussolino Torinese, Torino, 16 June 1904), mother of Prince Paul of Yugoslavia
Anatoly Pavlovich Demidov, 4th Prince of San Donato (San Donato 12/31 November 1874-Marseille 27 October 1943)
Princess and Countess Maria Pavlovna Demidova (Kiev, 3 February 1877 - Pratolino, 25 July 1955), married in Helsingfors (now better known by its Finnish name Helsinki), 30 April (Operating system) / 13 May 1897 Prince Semyon Semyonovich Abamelik-Lazarev (Saint St. Petersburg, 7 October 1857 - Narsan, Caucasus, 1 September 1916)
Prince and Count Pavel Pavlovich Demidov (San Donato, 4 February 1879 - Paris, 30 April 1909), unmarried and without issue
They ended up selling San Donato, and it was ceded on 5 November 1881 to Gaston Mestayer (a French business magnate), with the gardens sold separately to Nemesio Papucci and Rosselli Delegate Turco.
Owning hundreds of factories in Russia, millions of square kilometres of land and palaces in Russia, France and Italy, Pavel was considered as one of the richest men in Europe.
He developed the family fortunes and inherited Anatole"s title of Prince of San Donato after the latter"s death without legitimate issue in 1870 (with the title recognised by king Victor Emmanuel II of Italy two years later). He served with the Red Cross rather than the Russian military forces during the Russo-Turkish War and in 1883 he published the pro-Jewish "The Jewish Question in Russia".
