I have been working on my family tree over the last two years or so and have been able gather some more information on the family connections.If my information is correct then my grandfather and your father were third cousins. According to what I have been able to gather my great grandfather Hermilio Guerra was the grandson of Mr. Sebastian Guerra. Sebastian Guerra had a brother by the name of Salomon Guerra.
I recently came across a family tree project on myheritage.com which is being managed by Emil Steve Sabala who is a descendant of Mr. Salomon Guerra and around third cousin to you.Can you please send me your e-mail address to email@example.com so that I can share the information I've been able to gather so far with you. Thanks. Carlos Guerra
