I am helping a friend find his family. He came to the USA with his parents only when he was 5 (around 1975), and knows nothing about his family besides a few names on his birth certificate. Neither of us knows much about researching in Mexico. Looking for ANY help locating names, dates, locations of family members. His father's parents last names are Lopez and and Nunez (Finada). His mother's parents last names are Herrera and Aguilar.
