Looking for History,,,

Hello everyone,
I live in Hawaii now and I have family in SoCal. I was raised by the Pasillas family when I was six months old. I don't know much about my last name. But I have carried it well around the world. Can anyone help me find my roots? I tried to look for my real brother Palbo Zarate in San Bernardino. I did meet my mother Grace and brother 12 years ago. I want to see them again...Please help me...Tony
