Between 1840 and 1930, about 900,000 French Canadians emigrated to the United States.
A paper written in 1999 by professors at the Université de Montréal and Marianapolis College explains why so many French Canadians left Canada and it shows where they settled in New England in 1880 and 1930. “According to the 1980 American census, 13.6 million Americans claimed to have French ancestors. While a certain number of these people may be of French, Belgian, Swiss, Cajun or Huguenot ancestry, it is certain that a large proportion would have ancestors who emigrated from French Canada or Acadia during the 19th and 20th centuries.” To learn more, read French Canadian Emigration to the United States 1840-1930 by Damien-Claude Bélanger and Claude Bélanger.
