Narkissa Amvrosiyevna Rozanova (b. 16 July 1795 - 24 March 1878) was the daughter of Amvrosiy Rozanov, a patriarch of the Rosier family's Russian branch. Lady Rozanova moved to France at the age of eight, where she was integrated into French nobility with the help of her distant cousin, Minette Lestrange. In her late teens, Narkissa became the mistress of Lord Falco Lestrange, the second-born son of Corvus Lestrange (I) and Héloïse Beaufort.
