for Antoinettes younger son in Europe another story which shows him in Switzerland not USA:
Marti's paternal grandmother, the second wife of the Forgemaster and longtime Versamer Messmer Martin Bonadurer (1844 - 1879) was a Margaretha Rassel (1815 - 1894) of St.Antönien, a daughter of the acting in Trimmis, where 1834 died schoolmaster Josef Franz Rassel, and this - that sounds pretty incredible - was the son of 1793 during the French Revolution in Paris who died royal couple Louis XVI. and Marie-Antoinette. Her two children, the Dauphin (crown prince) Louis XVII. and his sister, the horrors of the revolutionary period have survived. They were kept under close guard in the notorious Temple Prison caught. The boy is abducted from there by royalists and with all due secrecy to the Grisons, to a secluded place as possible - has been spent - even after St.Antönien. In France it was called later, the crown prince died in prison of tuberculosis. He had just been swapped with any other seriously ill boy. Thus, the French heir lived undetected under the alias Franz Josef rattle St.Antönien and later as a schoolmaster in Trimmis, where he got married and the father of a nine-member group of children.http://www.bonadurer.ch/koeniglverw_teil%20I_d.htmlhttp://www.bonadurer.ch/ahnentafel_rassel_1_d.htmlhttp://www.bonadurer.ch/koeniglverw_presse_1_d.html

heart grave of Louis XVII. Saint-Denis
After Louis died, cut the royalist physician Jean-Philippe Pelletan out his heart and preserved it in alcohol. It came in a roundabout way through Austria, Italy and Spain in 1975 in the chapel of Saint-Denis, where it has since been kept in a chamber filled with alcohol crystal urn. In 2000, Belgian and German researchers presented based on genetic comparisons of cardiac DNA with genetic material from another, now living descendants of Maria Theresa, firm that the heart actually Louis XVII. belonged. The heart was eighth after a long odyssey on June 2004 buried in the Basilica of Saint-Denis.http://de.wikipedia.org/wiki/Louis_Charles_de_Bourbon,_dauph...
