This is an all-volunteer project dedicated to the advancement of genealogical research on Blanchard and similar surnames, using DNA testing as the main research tool. This is meant to supplement, rather than replace, the more traditional forms of genealogy research.

All male Blanchards (and those with similar surnames) are welcome to join. Comparison with the Blanchards of New York, Acadia, and Louisiana, as well as those of England, France, and the Low Countries may (or may not) reveal links between American and European branches of the various families. Also, anyone who wonders if he may be a male-line descendant of one of the lines covered in the study can perhaps identify his line by comparing his DNA signature (called a "haplotype") with the tabulated results.
