⌛ Looking For My Grandfather's Roots

Hello everyone. i was informed that my grandfather used to live in negros province. he was left in the train by his uncle when he was 7 years old. he was found by a certain couple from Batangas and from then on, he was adopted. we really want to trace his roots and try to meet our relatives. my mother tried that years ago. but the negros province did not find ways to help us. i hope fellow members can help me. my grandfather died 9 years ago without knowing who his brothers/sisters/relatives are. he told us that his real family name is MELO, but he used LAS PINAS when he was adopted by a certain family here in Batangas. i hope somebody can help me here. thank you so much.
