looking for steven roy jensen or family of steven roy jensen

My sister's and I have been looking for our father for over 30 years that I know of. I was sixteen when I sarted looking for him. I don't know much about him except that he use to live in coalinga,ca. and in modesto,ca. I also know that he got remarried and had another child, but I don't know if that child was a boy or girl. I also know that he is still paying back child support on my sister's and myself. I would like to get to know him and have him meet his grandbabies. If I can't meet him for some reason I would like to meet any family of steven roy jensen.
