DUBOSE, DUBOIS, DUBOISE, DUBOICE, DUBOYS, DUBOSC, DUBUSK, and other surname variants are welcome to join this Y-DNA paternal project. Many people with these surnames descend from Isaac DuBosc and Suzanne Couillandeau, French Huguenot refugees who settled on the Santee River in South Carolina in the 1680s...or from sons of Chretien and Cornelia DuBois, also Huguenots who emigrated to America in 1660 and settled in New York. Some researchers have suggested that these families share a common ancestor. Surnames included in the project include: DuBose, DuBois, Duboise, Duboice, DuBosc, Dubusk, Duboys, and other close variants.

For the results to be meaningful, participants will need to share their direct male line ancestry back to the earliest known DUBOSE/etc., either in the form of a pedigree chart, family group sheets, or electronic GEDCOM files.  Living persons should be excluded from the documentation.

Our surname project is registered at Family Tree DNA. Most of your questions concerning DNA testing for genealogy purposes can be answered at that site or by contacting me.
