Hi sstanger1,
She is Marie Robillard (1848-?) who married Horace Ducep about 1869 in or around Barrie, Ontario. If their marriage record exists, FamilySearch hasn't put it on line yet.
Marie was born in St-Lin, Quebec and her parents were Jean Baptiste and Felicite (Mercier dit Lajoie) Robillard of St-Roch-de-l'Achigan. Horace's parents were Joseph and Julie (Fontaine dit Bienvenue) Dieppe of Varennes, Quebec. Another researcher of this family told me Julie is of royal ancestry.
Joseph and Julie lived in Pittsfield, Massachusetts for a time during the 1840's. Horace was born there about 1844. Find them there on the 1850 census under Derseff. This family was very tough to research and trace due to the great number of spellings of their surname. I have more info if you need it.
