Good morning Linda. Valenzuela is new research for me as a matter of fact I finally found someone one who is related to me after three years of net research. I know that some of my family came from Sinaloa in eariler years but most came from Sonora. What you need to do is first get the closer family names and dates then look for records and remember sometimes the names are altered. If you have some full names and dates I might be able to help you a little as in eariler years there were many Valenzuela's in Santa Barbara and Bakersfield, CA. Also go to the Curch of Latter Day Saints (Mormon), they have all kinds of info to research. Have a good day. Eugenia
