I don't find that name on my tree, but that really isn't surprising considering that it only goes back three generations or so. My great-great grandfather, Paulo Soltero, was from Tecolotlan, Jalisco, and his father supposedly was a European-looking man that came from another Mexican state and had a German/European last name that could have been Zasueta. Once I do a little more research, I will get back to you if I find her in my family tree.
