[1] Siblings Omar and Abdullah Maute are descended from a Maranao warrior clan based in Butig, Lanao del Sur,[2] the town where they were born and spent their childhood.

[7] Philippine military sources state that the siblings' father, Cayamora Maute, was a senior official of the Moro Islamic Liberation Front (MILF).

[8] The Mautes, according to their relatives, later established connections with Ameril Umbra Kato, the founder of the Bangsamoro Islamic Freedom Fighters (BIFF) since both groups follow Wahhabism.

The siblings reportedly sent representatives to Kato after the BIFF leader suffered a hypertensive stroke which rendered the left portion of his body paralyzed.

[9] AFP Western Mindanao Command chief Lt. Gen. Carlito Galvez Jr. confirmed in December 2017 that all seven Maute brothers had been killed by the Philippine Army.
