My friend's grandfather was a GASTON BELLEGARDE. Her grandmother always told him that they were related to the GRIMALDI and that they fought fot the crown. They lost the trial. All the family comes from Egypt. I just know that Pierre Jean GASTON BELLEGARDE was born in Alexandrie on March 30th 1877 and that he was the son of Pierre GASTON BELLEGARDE and Nunzia GRIMALDI.
Maybe you can help us in our researches. What kind of documents do you have? Are you related to the GASTON BELLEGARDE.
