The Corson surname and its variants (e.g., Coursen, Corsa, Colson, Courson, and Vroom) has several origins. We seek to determine the relatedness and geocultural origins of these families worldwide.

Counting DNA results from all labs, the Corson surname project currently has more than 80 participants. Please visit the main project website (http://www.corsondna.com) for more information and contact the project coordinator if you have any questions.
