Manobo possess Denisovan admixture, much like the Mamanwa. Manobos also hold Austroasiatic ancestry. Mansaka The term "Mansaka" derives from "man" with literal meaning "first" and "saka" meaning "to ascend", and means "the first people to ascend mountains/upstream". The term most likely describes the origin of these people who are found today in Davao del Norte and Davao de Oro and some parts of Davao Oriental, specifically in the Batoto River, the Manat Valley, Caragan, Maragusan, the Hijo River Valley, and the seacoasts of Kingking, Maco, Kwambog, Hijo, Tagum, Libuganon, Tuganay, Ising, and Panabo. Matigsalug Bukidnon groups are found in the Tigwa-Salug Valley in San Fernando in Bukidnon province, Philippines. Their name means "people along the Salug River (now called the Davao River)." Although often classified under the Manobo ethnolinguistic group, the Matigsalug are a distinct subgroup. Sangil The Sangil people (also called Sangir, Sangu, Marore, Sangirezen, or Talaoerezen) are originally from the Sangihe and Talaud Islands (now part of Indonesia) and parts of Davao Occidental (particularly in the Sarangani Islands), Davao del Norte, Davao del Sur, Sultan Kudarat, South Cotabato, and North Cotabato. Their populations (much like the Sama-Bajau) were separated when borders were drawn between the Philippines and Indonesia during the colonial era. The Sangil people are traditionally animistic, much like other Lumad peoples. During the colonial era, the Sangil (who usually call themselves "Sangir") in the Sangihe Islands mostly converted to Protestant Christianity due to proximity and contact with the Christian Minahasa people of Sulawesi. In the Philippines, most Sangil converted to Islam due to the influence of the neighboring Sultanate of Maguindanao. However, elements of animistic rituals still remain. The Indonesian and Filipino groups still maintain ties and both Manado Malay and Cebuano are spoken in both Indonesian Sangir and Filipino Sangil, in addition to the Sangirese language. The exact population of Sangil people in the Philippines is unknown but is estimated to be around 10,000 people. Subanon The Subanons are the first settlers of the Zamboanga peninsula. The family is patriarchal while the village is led by a chief called a Timuay. He acts as the village judge and is concerned with all communal matters. History has better words to speak for Misamis Occidental. Its principal city was originally populated by the Subanon, a cultural group that once roamed the seas in great number; the province was an easy prey to the marauding sea pirates of
