This project supplements document-based genealogical research of individuals with the CO_RS_N surname (i.e., CORSON, COURSON, COURSEN, CORSEN, CORSSEN) and variants such as COLSON, CORSA, CORSAW, DECOURSEY, RACER, and VROOM in the following manner:

  1. To determine the geocultural origins of known family progenitors as precisely as possible.
  2. To connect individuals unsure of their male-line ancestry to a particular family.
  3. To deduce whether "brick-wall" ancestors are related to each other or to known progenitors (and if so, how).  Examples include:

As a DNA surname study, the project focuses on the Y-chromosome (carried by male-line descendants), whose characteristics identify only family lines, not individuals.

We are looking for more participants to submit DNA samples for testing or to help fund the cost of tests for their family members.  If the project interests you, please read about how to participate. Partial reimbursement of test costs for individuals from certain family lines is available.

This project is sponsored by the Corson/Colson Family History Association. If you have any questions about this project, please contact the project coordinator, Michael Corson (This email address is being protected from spambots. You need JavaScript enabled to view it.)
