I haven't found anything either, but you might try the mormon church genealogy library, they allow the public to access their libraries. No I am not a mormon but I had mormon in laws and mormons have the best genealogical information in the world as this is the whole crux of their religion.
Jesus Garcia was my great great grandfather too, and it would be interesting to find other distant relatives like you. This whole thing is interesting.
