Can you please help me to find my father here in Philippines. I only know only his name is Lamberto Santiago Jr. I don't know where he is, but he might be living in Cebu City.

How long has it been since you saw him ? What about other family members ?
Has he always been in Philippines ? Is he a citizen there ? Does his work require any professional license ?

Your best bet is Facebook, because finding people starts with people you know.
