About the children of the princess of Monaco, I really have not any more to share...It´s a pity, because she seems a very interesting figure, Eddie.
About Madeleine Senozan...I´m very interesting on this lady, but she seems elusive to me. Maybe here someone could provide us info. All that I know it´s that her full name was Madeleine Henriette Sabine Olivier Senozan de Viribille. She was a daughter of the former marquis of Viribille and she married Archambaud de Talleyrand Périgord, named Archambeau because he was a handsome man although not very clever...
He had not the wondreous mind of his brother, the famous Charles Maurice of Talleyrand
Madeleine had two sons and one daughter: Louis, Edmond Alexandre and Melanie. As far as I know, her daughter Melanie married a man of the Noailles family, and she was one of the several ladies-in-waiting of Empress Marie Louise.
