There is a profile for Luis Guzman on WikiTree but you would have to research a possible connection. If you are interested in joining WikiTree, you could create your father's family line, then search for birth, death, marriage and census records elsewhere ( familysearch.org is a good place to start) and put the pieces together. We cannot help you otherwise as you are posting as anonymous and we can know nothing about your father or "his side" without more details. Unfortunalely, resembling someone does not make you related necessarily. :-)
