The Perea/Pereira DNA Surname Project is asking that all individuals with the surname Perea, Pereira, Pereyra, and Perera that have roots in New Mexico, Mexico, Brazil, Portugal, and Spain, take part in a study to help fill in the gaps that the paper trial has left behind.
Although this project is focusing on Pereas, Pereiras, Pereyras, and Perera from New Mexico, Mexico, Brazil, Portugal, and Spain, it would be interesting to see how Pereas, Pereiras, Pereyras, and Perera from out side New Mexico, Mexico, Brazil, Portugal and Spain match as well.
