I'm looking for my father

My name is Serena Lopez and I'm 29 years old married with 2 kids. I have never really met or talked to my father, since I was a little girl. My mother really never wanted to speak about him so all I know is little info. about him. His name is Ralph Carlos Carabajal he is 53 years old and was born in Mexico. I was born july 1980 in eugene, oregon. Thats about all I know of him. Please help me find him. Thank you so much
