Hi, Elden. My name is Elmer Lazon Bonilla. My father's name is Eleuterio Bullo Bonilla. My grandfather is Alquino Sintorio Bonilla and his father, my great grandfather is Pedro Bonilla. We are residents of Surigao City. I believe my great grandfather and your grandfather are not the same person. I just learned now that there are other bonilla families outside surigao city. I really don't have knowledge of our ancestry, in fact, there are many other bonilla relatives here who are not descendants of my great grandfather. We only know that we are relatives because of our name, but we cannot trace our links anymore. Hope someday, we can have a family tree that will link us all to a common root.
