Did child of marie antoinette escape the french revolution and assume a new identity?

Louis-Charles died on 8 June 1795. The next day an autopsy was conducted by Pelletan, at which it was stated that a child apparently about ten years of age, "which the commissioners told us was the late Louis Capet's son", had died of a scrofulous infection of long standing. "Scrofula"[7] as it was previously known, is nowadays called Tuberculous cervical lymphadenitis referring to a lymphadenitis (chronic lymph node swelling or infection) of the neck (cervical lymph nodes) lymph nodes associated with tuberculosis.[8][citation needed]
During the autopsy, the physician Dr. Pelletan was shocked to see the countless scars which covered the body of Louis-Charles. The scars were the result of the physical abuse the child suffered while imprisoned in the Temple.[9]
Louis-Charles was buried on 10 June in the Sainte Marguerite cemetery, but no stone was erected to mark the spot. A skull was found there in 1846 and identified as his, though later re-examination in 1893 showed it to be from a teenager and therefore unlikely to be his.[10]
Heart of Louis-Charles

Following a tradition of preserving royal hearts, Louis-Charles's heart was removed and smuggled out during the autopsy by the overseeing physician, Philippe-Jean Pelletan. Thus, the heart of Louis-Charles was not interred with the rest of the body. Dr. Pelletan stored the smuggled heart in distilled wine in order to preserve the heart. However, after 8 to 10 years the distilled wine had evaporated, and the heart was further kept dry.[9]
After the Restoration in 1815, Dr. Pelletan attempted to give the heart to Louis-Charles's uncle, Louis XVIII, however he refused because he could not bring himself to believe that was the heart of his nephew. Dr. Pelletan then donated the heart to the Archbishop of Paris, Hyacinthe-Louis de Quélen.
Following the Revolution of 1830, and the plundering of the palace, the son of Pelletan found the relic in the remnants of the palace and placed it in the crystal urn, in which it still resides today. After his death in 1879, Eduard Dumont received the heart.[9]
In 1895, the nephew of the Archduchess Maria Theresa of Austria-Este, Don Carlos de Bourbon, a pretender to the throne of Spain accepted the relic from a friend of Eduart Dumont, Paul Cottin. The relic was held near Vienna, Austria at the castle of Frohsdorf. The son of Carlos, Jaime, Duke of Madrid, in 1909 inherited the heart, and gave it to his sister, Beatriz.[1][2]
Finally two granddaughters of Don Carlos offered the heart to the president of the Memorial of Saint-Denis in Paris, Duc de Bauffremont, where he put the heart and its crystal urn in the necropolis of the Kings of France, the burial place of Louis-Charles's parents and other members of the French royal family.[9]
In December 1999, public notaries witnessed a section of the heart muscle of the aorta removed from the rest of the heart, and the transfer of the samples into a sealed envelope, and then the opening of the sealed envelope in the laboratory to be tested. Scientists using DNA samples from Queen Anne of Romania, and her brother Andre de Bourbon-Parme, maternal relatives of Louis XVII, thus proved the young royal's identity.
