Hi Leonor. My name is Omar and I currently reside in California. From what I know so far my grandparents came to the states in the 80's from a little town called Caurio de Guadalupe in Michoacan. His name is Francisco and I just found out that he has a brother that lives in Tijuana and his name is Genaro. That's as much as i know but from the different conversations I have had with my grandfather he himself wouldn't even know where to begin to look for ancestors because of how spread out they are. I hope this information helps you. Good Luck.
