Incredible though it may seem, the elder Kalantiaw I gave his name to both his sons, Kalantiaw II and Kalantiaw III. Kalantiaw II was not the father of the more famous Kalantiaw III but his brother!
Mahirap paniwalaan na ibinigay ng matandang Kalantiaw I ang pangalan niya sa kaniyang dalawang anak, Kalantiaw II at Kalantiaw III. Si Kalantiaw II daw ay hindi ama ng mas sikat na si Kalantiaw III kundi kaniyang kapatid!
