Brajesh Singh

His first wife was Kunwarani Laxmi Devi, followed by Leela, an Austrian woman with whom he had a son named Victor Singh. Victor later moved to England, where he became a photographer. In 1963, while recuperating from bronchitis, Singh met Svetlana Alliluyeva, the only daughter of Joseph Stalin. The two fell in love while Singh was critically ill with bronchiectasis and emphysema. The romance deepened while the couple were recuperating in Sochi near the Black Sea.
Singh returned to Moscow in 1965 to work as a translator, but he and Alliluyeva were not allowed to marry. He died the following year, on 31 October 1966. In an interview on 26 April 1967, Alliluyeva said that she considered Singh to be her husband but that Aleksei Kosygin never allowed them to legally marry. Provided by Wikipedia
