I have a few things to comment on after reading this.
One, I have seen a picture of the Yussupov grave in Paris and the husband, Count Felix, is not buried there. It is only Zinaida, Felix, Irina, Bebe, and her husband. Isn't the husband buried in Italy?
Also, I read in the book by Greg King that though Felix smuggled those paintings out of Russia, he got no money for them, he was swindled by a crooked American dealer. He even came to the US and sued but lost. I usually hear he lived off those, but it is not true!
They had sold some jewelry, and had some property in western Europe, and had the Irfe business, but were they not almost broke when they sued MGM in 1934?
I still can't believe Felix encouraged the duel. He was so honestly heartbroken over the death of his brother the effect it had on his mother. After his death, Felix discovered some letters showing his brother had been under the influence of a French psychic who assured him he would win the duel. I can believe this considering how into spiritualism and such they all were.
