I wiki'd the word Lumapas and it led me to a place in Brunei.
Here is the quote from wiki:
Lumapas is a mukim (or barangay) in the Brunei-Muara district of Brunei. It is located in the south of the Brunei-Muara district, bordering the water village mukims and Mukim Kianggeh to the north, Mukim Kota Batu and Pulau Berambang (Kota Batu) to the north and east, Limbang, Sarawak (Malaysia) to the east and south, Mukim Pengkalan Batu to the west and Mukim Kilanas to the west and north.
History 101 tells us that filipinos may have come from Malaysia or Indonesia. However, this information leads me to think that maybe the Lumapas origin migh have come from Brunei. :-)
