the Villalobos expedition, some Spaniards were able to reach the mouth of the Pulangi where they were informed by the inhabitants that the chief was called “Sarriparra”. This being a variation of “salipada” or “saripada”, it can be surmised that the chief was the Sharif Maka-alang; especially if it is considered that not only does a Tarsila explicitly state that the Sharif had such a title but that such a title was not found among his immediate successors. 3. Datu BangkayaHe was a son of Sharif Maka-alang. In 1574, Guido de Lavezaris wrote to the Spanish King that the chief of Mindanao River wanted to become a friend of the Spaniards. In another Spanish report dated 1579, this chief is referred to as “Asulutan” (Arabic, As-sulutan) with the information that he was a father of Diman Sankay and that he had already died. This refers probably to Datu Bangkaya who by 1574 must have been reigning for some time, since in 1579, his son Dimansankay, was considered by the Spaniards to have been “an old man”. Datu Bangkaya could also have been the ruler in the Pulangi who was reported to have died in 1578. 4. Datu Dimasankay He was a son of Bangkaya. Spanish reports say that he was ruling in 1579 and that he was an old man. The leading datus of the Iranuns and Maranaos all claim descent from him. 5. Datu SalikulaHe was the half-brother of Dimansankay and also known as Gugu Salikula. Up to early 1597, he appeared to be a lading chief of Maguindanao, Dimansankay being dead at that time. According to tarsilas, he married a Sulu princess, and therefore he might have been the Maguindanao chief seen in Jolo in 1597 where he was supposed to have been banished for being “restless and rebellious” and who was further described as a brother-in-law of the Sulu ruler and an uncle of the Maguindanao Rajah Muda (erroneously called “King”) by the Spaniards. He was chief around 1585 to 1597. 6. Kapitan Laut Buisan He was a younger half-brother of both Dimansankay and Salikula; he was sometimes called by the title “Katchil”. His rule began around 1597 when he displaced Salikula; he controlled his nephew, the Rajah Muda, a son of Dimansankay. He must have been chief at least up to 1619, since Dutch sources mention relations with the immediate predecessor of Kudarat at this date.
