My father's name is Gregorio Sierra and my grandfather was Gregorio Sierra Torres and my great granfather was Pitacio Sierra. I'm looking for any information on my grandfather or greatgranfather. My grandfather was a police officer in Puerto Rico with multiple children. We have so far counted around 25 or more offsprings from my grandfather. If you have any information please let me know. I'm trying to trace our family history and have little information on them.
