"Prince Boris's only son, Prince Nikolai Borisovich Yusupov (October 12, 1827, Moscow - July 31, 1891, Baden Baden), Marshal of the Imperial Court, was much like his uncle Nicholas I, a patron of arts. He first served in the chancery of Nicholas I. He bought a large collection of jewelery, including a 36 carat (7.2 g) diamond known as Morocco Sultan. The Prince later spent much of his time in southern Europe because of poor health, while also serving the tsar as a diplomat. While in Europe he bought much to adorn his palace on the Moika, including collections of violins and paintings. He married Countess Tatiana Alexandrovna de Ribeaupierre (June 29, 1828 - January 14, 1879), a lady-in-waiting to the Empress, daughter of Comte Alexandre de Ribeaupierre and wife Ekaterina Mikhailovna Potemkina, another niece of Prince Potemkin. The prince was also a talented musician and composer and was a member of several musical societies. In 1866, he published a book about the Yusupov history On the Family of the Yusupov Princes. A Collection of Their Life Stories, Charters and Letters of the Russian Sovereigns to Them.
When Prince Nicholas Yusupov II died in 1891, he was succeeded by his daughter, Zenaida, who was considered a legendary beauty at the time, as well as one of the richest; her suitors included the crown prince of Bulgaria. Princess Zenaida Nikolaievna Yusupova (September 2, 1861, Saint Petersburg, Russia - November 24, 1939, Paris, France) married Count Felix Felixovich Sumarokov-Elston (October 5, 1856, Saint Petersburg, Russia - June 10, 1928, Rome, Italy), General Governor of Moscow (1914–1915), son of Count Felix Nikolaievich Sumarokov-Elston. They married on April 4, 1882 in Saint Petersburg, Russia. After his father in law died, Felix was granted a special permission from Tsar Alexander III of Russia to carry the title Prince Yusupov and Count Sumarokov-Elston and to pass it to his and Zinaida's heir. Prince Felix was appointed adjutant to Grand Duke Sergei Alexandrovich in 1904 and commanded the Guards Cavalry of the Imperial Guards, and in 1914 he was appointed Governor General of Moscow. At the beginning of World War I the Yusupovs owned more than 100,000 acres (400 km²) of land and their industries included sugar beet factories, brick plants, saw-mills, textile and cardboard factories, mines and distilleries, in addition to more than 16 palaces and estates."
So the answer appears to be yes.
I would imagine that she would be considered a legendary beauty at any time...
