Born on 6 October 1914, in Tiflis, Georgia, Russian Empire as Princess Leonida Bagration of Mukhrani, she was a daughter of Prince George Bagration of Mukhrani and his Polish wife Helena Sigismundovna, née Nowina Złotnicka (1886-1979) [REF].
The Bagration family's genealogy traces back at least to the medieval era in its male line and hundreds of years further back as rulers in the female line [REF].
