About us

The We Are Cousins DNA Project is for anyone interested in Y-DNA and mtDNA research whose paternal and maternal roots are from the States of Nuevo Leon, Tamaulipas, Coahuila, and South Texas. Our goal is to identify the YDNA for every last name found in South Texas and Northeastern Mexico and identify different DNA lineages for any given last name. This project will also focus on identifying the mtDNA of their wives.
