My family is from La Lobera Michoacan and the other towns you mentioned are very close to La Lobera. I did notice that you spelled it La Ladera, not La Lobera, but the other towns you mention are close to La Lober. My grandfather was Ines Calderon and my father is Leonel Alfonso Calderon, both lived in La Lobera Michoacan too. It will be interesting if we are related. My mother was raised in Santa Ana Maya Michoacan, so we are definitely talking about the same geographical location. Guanajuato is very close to Michoacan, so I think we have made a contact!
