HI, I have just started researching the Cadena family. My grandfathers name was Jose Luis Cadena Garcia. He was born in Melchor Muzquiz, Coahuila, Mexico I beleive. And his Father was Pedro Cadena and my grandfathers grandfather was believed to have been named Francisco Cadena. Can anyone give me some tips on how to go about this? This is an assignment for a history class Im taking this semester..and Im super excited. Thank you!
