The Butuanon and Tausug languages were closely-related; after all, they belong to the same branch of the Visayan language group, the southern group. According to A. Kemp Pallesen's Culture Contact and Language Convergence (through this post), the Tausugs of Sulu Archipelago were descendants of intermarriages between Sama merchants and Butuanon-speaking women. On the other hand, according to the other sources (J.T. Peralta, William Henry Scott & Dr. Robert Fox), Tausug people were basically migrants from the Butuan area around 11 AD (as my source believed).
So, here's the question: what if the ancestors of Tausug people decided to go inland deep in the Agusan Valley instead of going to Sulu Archipelago, as suggested by the second theory? What would their relationship with the local Manobo clans that they've encountered? How it would affect the history of both Sulu Archipelago and Agusan Valley?
