The main finding of this study is that the community has been in the their ancestral territory for at least fifty-one generations or approximately 1,580 years of uninterrupted occupancy. Reenforcing this genealogical claim are other basic items like the stories on the sixty-five names of places and sites, and their custom and tradition on the acquisition of their domain and the use of its resources. The actual presence of their traditional leaders in the various communities further enhances the claim. The story about the 1975 uprising is a bonus, not anymore necessary to determine the basis of ancestral domain claim, but enables us to appreciate how strongly the Matigsalugs feel about the security and defense of their community.
