The INA (Institut national de l'audiovisuel) website (France) has footage of the return to Corsica of the remains of Carlo Bonaparte, Napoleon Bonaparte's father, which dates from 15 May, 1951. It would appear, however, that the journalist has made a mistake in suggesting that the mortal remains of Caroline Murat are also being returned as part of ceremony. As far as we can make out, it seems more likely that it is the wife of a later Prince Murat, who was also Princesse de la Moskowa, who was present at the ceremony.
