Even if you can't read French, tracing French-Canadian and Acadian ancestors can be easier than many people expect due to the excellent record keeping of the Roman Catholic Church in Canada and the remarkable level of French-Canadian records preservation. Generally, all you need to begin a search are the names of the couple married in Quebec, or the Maritime Provinces of Canada (New Brunswick, Nova Scotia and Prince Edward Island), and parts of Maine (U.S.), and an approximate marriage date. From there you can often extend the family line back many generations, in some cases to the village or parish of origin in France. It's also not uncommon to find ancestors in the border states such as Vermont and New Hampshire living in the United States, but marrying or baptizing children in Canada...or just moving back and forth across the border.
