There are many "Francisco Babauta" in Guam but another surname is needed to help you.
Was Babauta his father's surname?
Also if you can state where you were born, it may help someone to help you by checking if your Father was living in the place where you were born. My Francisco surname was not Babauta.
Also how old do you think he was when you were born?
in fact, provide as much information as you can. I have a long list of names in my personal files, some not related, to me, but may be related to you. But I need more information. What was his middle name, his mother's name, city or town or village where you were born, aproximate date of his birth and yours. No need for day and month, just years.
