Are there any Aguieras out there that have had their DNA test? My grandfather was adopted and the family mentions his father being Aguilera from Guanajuato. If you do have an Aguilera DNA test feel free to contact me as I would like to know if we really are Aguileras. I've had my y-DNA test results for a couple of years now. I'm also a participant of Gary Felix's Mexico DNA Surname project.
