Surname project for Burchfiel, Burchfield, Birchfield (and variations) families. The project is open to all who are interested in working together to find their common heritage through sharing of information and dna testing. This project welcomes Y-DNA, mt-DNA, and atDNA (Autosomal/Family Finder) tests from any Burchfiel, Burchfield, Birchfield descendant. The goal of this project is to identify which family branches are related to each other, to confirm paper-trail evidence and traditional genealogies, and to help focus further documentary research.
