From the New England Historic Genealogical Society's The Weekly Genealogist:

A journalist from French television channel TF1 is seeking French families who, as part of their genealogical research, are trying to connect with relatives whose ancestors immigrated to the United States or Canada between the 16th century and the beginning of the 20th century. If you or someone you know has been contacted by anyone in France for information about possible relatives in the U.S. or Canada, or if you know of any French families seeking information about U.S. or Canadian connections, please contact Eugénie Cohen at ecohen.cpi@tf1.fr
