I have been searching for my great great grandparents, the family of my great grandfather Jean Marie Chancerelle, who immigrated to US in 1870. His father was Jean Chancerel and mother Marie Maugros married about 1847 likely in Trevenuec, St Brieux, Cotes du Nord, France. They had five children, Toussaint Marie b 1848, Joseph Marie b 1850, Marie Josephte b 1851, Jean Marie b 1853, and Pierre Marie b 1855. I have no other information and would appreciate any lead.
