My name is Monica and my grandfather's name was Guillermo Gonzalez. He lived in a small ranch in Durango MX. I saw that you were asking about a Maria Gonzalez. My grandfather had either 17 or 16 brothers and sisters, some of which I don't know the names of. Were you able to find any information about your relative? If you did I was wondering if you could share to see if we might have overlap. Thank you so much and I appreciate the help.
