Upon his death, the Prince-Caesar's extraordinary titles devolved upon his son, Prince Ivan Fyodorovich Romodanovsky. He was related to the tsar through his sister Feodosiya, the wife of Eudoxia Lopukhina's brother, and through his wife Anastasia Saltykova, Ivan V's sister-in-law. Despite his high position, Prince Ivan was not well suited for active service. Under Peter II of Russia, he served as governor of Moscow but retired a year before his death, which followed in 1730, whereupon the family became extinct. Princess Catherine, his only daughter and heir, was married by her first cousin, Empress Anna, to Gavrila Golovkin's son, thus bringing the Romodanovsky estates under control of that Chancellor of the Russian Empire.
