Answer by taking a quote from the following article:

Vaslav Nijinsky (also Vatslav; Russian: Vatslav Fomich Nizhinskii; Russian: ['vatsl@f f@'mjitc njI'zinskjIj]; Polish: Waclaw Nizynski; 12 March 1889/1890 - 8 April 1950) was a ballet dancer and choreographer cited as the greatest male dancer of the early 20th century.

Nijinsky spent his summer after graduation rehearsing and then performing at Krasnoe Selo in a makeshift theatre with an audience mainly of army officers. These performances frequently included members of the Imperial family and other nobility, whose support and interest were essential to a career. Each dancer who performed before the Tsar received a gold watch inscribed with the Imperial Eagle. Buoyed by Nijinsky's salary, his new earnings from giving dance classes, and his sister Bronia's employment with the ballet company, the family moved to a larger flat on Torgovaya Ulitsa. The new season at the Mariinsky theatre began in September 1907, with Nijinsky employed as coryphee on a salary of 780 roubles per year.  He appeared with Sedova, Lydia Kyasht and Karsavina. Kchessinska partnered him in La Fille Mal Gardee, where he succeeded in an atypical role for him involving humour and flirtation. Designer Alexandre Benois proposed a ballet based upon Le Pavillon d'Armide, choreographed by Fokine to music by Nikolai Tcherepnin. Nijinsky had a minor role, but it allowed him to show off his technical abilities with leaps and pirouettes. The partnership of Fokine, Benois and Nijinsky was repeated throughout his career. Shortly after, he upstaged his own performance, appearing in the Bluebird pas de deux from the Sleeping Beauty, partnering Lydia Kyasht. The Mariinsky audience was deeply familiar with the piece, but exploded with enthusiasm for his performance and his appearing to fly, an effect he continued to have on audiences with the piece during his career.  In subsequent years, Nijinsky was given several soloist roles. In 1910, Mathilde Kschessinska selected Nijinsky to dance in a revival of Petipa's Le Talisman. Nijinsky created a sensation in the role of the Wind God Vayou.

Did he ever perform with his family?
