About us

The goal of this project is to establish the YDNA haplotype and haplogroup SNP branches for individual Dunn lines and Dunn family subgroups.  This goal is accomplished by ordering YDNA STR tests, individual SNP tests, and BIG Y700 for men born with the DUNN surname.  BIG Y700 has become an essential YDNA test for genetic genealogy.
