Hi sir; its possible that we are relatives. My great grandfather was from Arayat Pampanga, Philippines; I just dont know his name but he married my great grandma whose surname is "Sinca" also from Arayat, Pampanga Philippines; although my grandfather (Teodulo Sinca Espino) was born in Arayat, Pampanga Philippines, his parents raised him together with his siblings in San Jose Occidental Mindoro Philippines during world war 2. i'm very much interested to know more about my ancestry and to be able to connect to other relatives. i hope that soon, we can exchange more information about our surname and it's history. thank you.
