French Canadians of Quebec are a classic example of founder population. Over 150 years of French colonization, between 1608 and 1760, an estimated 8,500 pioneers married and left at least one descendant on the territory.[12] Following the takeover of the colony by the British crown in 1760, immigration from France effectively stopped,[13] but descendants of French settlers continued to grow in number due to their high fertility rate. Intermarriage occurred mostly with the deported Acadians and migrants coming from the British Isles[citation needed].
