I've fond this about mme Schebeko: She was born in 10 July 1871 in Andreievskoie, Yaroslav. She named Princess Anna Anatolievna Kourakine, daugther of Prince Anatole Alexandrovitch Kourakine and of Princess Elisabeth Mikhailovna Wolkonsky. In 14 June 1891 she marry with Nicholas Nicholaievitch Schebeko (born in 1863) and had two sons: ALeksandr (1892) and George (1895). All of them survived the revolution..
