Hello, I am searching for information on the ETIENNE family of France. My great grandmother was Marie Mathilde MERCIER (born 4 february 1874 in France). She was married to Seraphin Edmond LEROUX (born 29 december 1869 in France). His father was Seraphin LEROUX (born approximately 1821 in France), and his mother was Marie ETIENNE (born approximately 1827 in France). Any information is greatly appreciated. Thank you.
