I have already posted on Marie-Antoinette's adopted children so I was delighted to find an article with further information. Most people are unaware that the Queen adopted a young African boy and had him raised in the palace. To quote:
ShareIn 1787, Marie Antoinette was presented with an unusual gift from the famous traveller Chevalier de Boufflers, who had recently returned from Senegal. He offered the Queen a parrot (to join the vast and rowdy crew of pets that already terrorised Versailles) and a young Senegalese boy. Normal practice at the time would have been to dress the boy up and take him into service (much like the boy pictured in the above painting), but on this occasion Marie Antoinette had him baptised and renamed Jean Amilcar, and instructed one of her houseboys to look after him.
All three of these children remained with Marie Antoinette as the royal family was ousted from Versailles in October 1789, and moved to the Tuileries Palace in Paris. At this point, Jean Amilcar was placed in an institution for children at Saint-Cloud, and Marie Antoinette sent monthly payments to provide for his upkeep. When she was moved from the Tuileries to much tighter imprisonment at the Temple, she was unable to keep up these payments, whereupon it was said that the boy was cast out by the charity, and he starved to death on the streets.
