My Great-Grandmother's maiden name was Brambilla. She was born in Guadalajara, Jalisco. The family is from Milan, Italy. There are many legends, rumors, and stories of how the family came to Jalisco- one of which says that there were three Brambilla sons who came to Mexico, one of them seperated in Veracruz, and the other two went to Jalisco. Another legend is that they were italian pirates. I don't know the credibility of the stories, and would be interested in finding people with this name.
