Kapitan Laut Buisan
Kapitan Laut Buisan was a younger half-brother of both Datu Dimansangkay and Datu 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 Dimasangkay. He must have been chief at least up to 1619, since Dutch sources mention relations with the immediate predecessor of Qudarat at this date.
