I wanted to know how were the relations between the Romanovs and Countess Elena Stroganoff-Sheremetieff the daughter of Maria Nikolaivena.
Actually Elena was not
Countess by her husband as Vladimir Sheremetev had not a title of Count, he was from the poor branch of the Sheremetevs.
It has been several years since I read the memoirs of Prince Christopher of Greece, however, I'm certain he recalled meeting her on at least one occasion, I believe while at Pavlovsk with his mother, Queen Olga, and seemed to think Elena was very kind and attractive, and referred to her as "Cousin Helen." Perhaps, she was kind to him because he was a Romanov cousin (via his mother) and she needed their financial assistance?
I've came across some mentions of Elena in the Romanovs journals and I can't say they told about anything really harsh. She indeed was always in debts and lived on mercy of her half-sister Duchess Evgenia of Oldenbourg but anyway Elena was a
cousin for the Romanovs.
By the way, Elena was a first platonic crush of famous GD Konstanin K. aka KR in the end of the 1870s !!...In the 1910s his eldest son Ioann even made visits to her tomb (she died in 1908) and called her "Aunt Elena Milashevitch" (she married secondly a Milashevitch in 1896).
I've been searching for her pictures for some time but still nothing. ((
