At the age of fourteen, during French occupation of Madagascar, Razafinandriamanitra became pregnant by a French soldier. On 28 February 1897 the monarchy was abolished and France took complete control over the Malagasy government. Razafinandriamanitra accompanied her mother and Princess Ramasindrazana to join her aunt, Queen Ranavalona III, in Toamasina after she was removed from the palace by French troops. Together they boarded the ship "La Peyrouse" and left for Réunion to live in exile. They arrived in Pointe des Galets where they were met by an angry crowd. They were taken from the port city to Saint-Denis and took up residence in the Hotel de l'Europe. On 1 May 1897 Razafinandriamanitra gave birth to a daughter, Marie-Louise. Razafinandriamanitra died on 6 May 1897, five days after giving birth. She was buried in a cemetery in Saint-Denis. Her daughter was later adopted by the queen and became the next heiress presumptive.
