Mga Kaigsoonan,
I am going to jump start the myth of our family name post.
According to Prudencio Sr., Our great grandfather who settled in Moalboal, Cebu from Sevilla, Spain during the Spanish rule in the Philippines, changed his last name from Cristobal to Tubalado. He did this to be able to stay with his family and escape from being deported back to Spain during the American occupation.
