After the 9th century the family allied and intermarried with the Vikings or Northmen, when they were recorded as an ancient Norman family with seats and estates.

The search for the Northwest passage continued. Migration from France to New France or Quebec, as it was now more popularly called, continued until 1759. By 1675, there were 7000 French in Quebec.
