Brigham Young University in Utah offers several free online genealogy courses, including one about France. While this course is not for credit, it is a great way to learn something new at no cost. To review the lessons, you must first enroll online. You will then work at your own speed and choose the time and place. When you have completed the course, you will have learned how to identify the place of origin of your ancestors, explained why you must analyze your information, and discussed some French emigration groups and sources to help you find your French ancestor’s place of origin.
A list of courses, including the French course, is available on BYU’s Independent Study web page.
