Out of this Bornean Tribe of the Dumangsil and Balkasusa Clan was born the ancestry of Lipa and as later on their descendants spread out towards Laguna de Bay and Bicol Peninsula. The remains excavated from their ancient settlements in Butong, Taal, Calatagan Bay Area and Balayan attest to the fact of their presence in the said site at least in the latter part of the 12th century down to the coming of Goiti and Legaspi in Batangas in 1570. The flourishing trade relations between these early Batangueños with a number of Chinese merchants prior to the Spanish conquest explained the presence of hundreds of Chinese wares from potteries to stonewares and vases of Song dynasty period to the latter part of the 16th century, in the burial grounds at Calatagan sites of Pulung Bakaw, Kay Tomas, Pinagpatayan I and II at Butong, Taal Batangas.
