Jeanne Marguerite Feuvrier

A Lincolnshire relative of mine, Edward Stanton (born in Heckington in 1784) is grandfather of a London pianomaker, Joseph Stanton. In 1896, in London, Joseph Stanton married Jeanne Marguerite Feuvrier. She was born in about 1869, in France, a daughter of Gustave Feuvrier, a watchmaker. I am trying to trace her ancestors, but without luck so far. There are many Feuvriers in the area close to the Swiss border. Any suggestions would be welcome! Andrew Wilson
