The descendants of Tabunaway are called dumatus, which is the future tense of the verb datu. The dumatus are well known, and I have met several of them. Chief among them I mention Datu Mawlana Sa-Magindanao and Datu Kali Adam. The former has lately been favored with the honorary title of datu by Datu Mastura, because his mother was a datu's daughter and he personally deserved the honor. Both Datu Mawlana and Datu Kali claim that Sharif Maraja, the father of Tabunaway, was an uncle of Sharif Kabungsuwan and that he and his children were Mohammedans prior to the arrival of Kabungsuwan, though their people were not so until Kabungsuwan converted them. The story that the angels brought paradise to Mindanao does not appear in the other manuscripts, but it is generally believed by all the datus and people of Magindanao. I heard both Datu Mastura and Datu Mawlana Sa-Magindanao affirm the fact. They say that a part of the white earth of paradise was left in the hill behind Cotabato and they call it the sacred dust. It was the custom in Magindanao to bring this earth before the new sultan after his appointment that he might step on it for the confirmation of his sultanate. They believed no sultan could be successful and prosperous in his reign unless he performed this rite. The last sultan who obeyed this custom was Sultan Untung Qudratul-Lah, Datu Mastura's father, during the latter part of whose reign the Spaniards came into Magindanao and occupied Cotabato. The later three sultans did not perform this rite; this the Moros cite as the cause of the decline of the sultans' power and the lack of prosperity in the country. They believe this white earth still exists in the hill of Cotabato, but nobody can find it except the oldest living dumatus whose forefathers have not intermarried with either datus or the common people, and to whom the secret has been handed down from Tabunaway. This they keep away from everybody except their children. The dumatus are a privileged class of people, and claim they can follow any datu they choose, and that they should not pay any tribute. They assert that when Tabunaway resigned his sovereignty in favor of his older brother, Kabungsuwan, he reserved this privilege for his children, which privilege Kabungsuwan promised to respect. For these reasons the dumatus keep their own records of the history of their country, and the genealogy of their line. Sambug, who is mentioned here, is stated to be the son of Tabunaway. Manuscript No. III states that Kabungsuwan had a son named Sambgan, who was born in Juhur. Whether these two are one and the same name or not it is very difficult to say. Probably they are two different names. LITERAL TRANSLATION OF MANUSCRIPT NO. IV THE GENEALOGY AND HISTORY OF THE PEOPLE OF MINDANAO
