According to the research done up to now by the World Association of Laporte’s & St-Georges du monde, there are 11 known lineages of Laporte and Quebec-descended St-Georges in North America. The majority of these Laporte and St-Georges in America have the same common ancestor in the person of Jacques de LaPorte dit St-Georges (1st lineage). The latter was born on March 5, 1627 in Nocé, France (in the former region of Perche, now Normandy).
