During the mid-18th century, French Canadian explorers and colonists colonized other parts of North America in what are today Louisiana (called "Louisianais"), Mississippi, Missouri, Illinois, Wisconsin, Indiana, Ohio, far northern New York and the Upper Peninsula of Michigan as well as around Detroit. They also founded such cities as New Orleans and St. Louis and villages in the Mississippi Valley. French Canadians later emigrated in large numbers from Canada to the United States between the 1840s and the 1930s in search of economic opportunities in border communities and industrialized portions of New England. French-Canadian communities in the United States remain along the Quebec border in Maine, Vermont, and New Hampshire, as well as further south in Massachusetts, Rhode Island, and Connecticut. There is also a significant community of French Canadians in South Florida, particularly Hollywood, Florida, especially during the winter months. The wealth of Catholic churches named after St. Louis throughout New England is indicative of the French immigration to the area. They came to identify as Franco-American, especially those who were born American.
