I was just wondering if anyone might know of some type of Marquis de Bergerac in France? A great great......Aunt of mine married a Marquis in France after her first Husband died, Prince Gudonov of Russia. Her birth name was Margit (Marguerite) Thurner from Hungary and she was quite a well-known opera singer in Paris. Her second husband, the Marquis, was her benefactor and later she married him. I'm looking in the period of the mid to late 1800's. Anyone know of any Marquis de Bererac (the spelling or exact title name is not certain) as my grandmother only remembers so much. Any help is appreciated.
