Someone in your family has a family tree built back to Jose?
Have you done any research? Since the family has been in the US for such a long time, there are many descendants around.
Ask the person with the tree how many have been in contact.
I have a fairly recent tree and found many long lost cousins.
You could always start your own tree and see what you find. But beware, it does get addicting.
