"

Cui married Mal'vina Rafailovna Bamberg (Мальвина Рафаиловна Бамберг) in 1858. He had met her at the home of Alexander Dargomyzhsky, from whom she was taking singing lessons.[1] Among the musical works Cui dedicated to her is the early Scherzo, Op. 1 (1857), which uses themes based on her maiden name (BAmBErG) and his own initials (C. C.), and the comic opera The Mandarin's Son. César and Mal'vina had two children, Lidiya and Aleksandr. Lidiya, an amateur singer, married and had a son named Yuri Borisovich Amoretti; in the period before the October Revolution Aleksandr was a member of the Russian Senate.[2]
