I'm researching my grandmother's family, last name Duval from the Bracebridge area. Her name was Mary Selina Duval and her parents were Onesime "John" Duval and Mary Flavie Duval nee Rouille. They were from Quebec, and were Roman Catholic attending St. Joseph Church in Bracebridge. I've found them on the 1881 census for Bracebridge, but their last name was entered incorrectly as "Gervan". I found them by going through the census page by page. They were listed as Onesime, Mary, Joseph, Napoleon, M.C.Gervan.The 1891 census seems to have different districts than the 1881. Could you please help me find them on the 1891 census as well as anything about the family. Thank you for any help you might be able to provide me with.Margaret Abram
