Awdur: Thomas Jones Pierce

Gyrrwyd ef o Wynedd gyda'i frawd, Ieuaf, gan Hywel Dda pan fu Idwal Foel f., yn 942, eithr cawsant ddychwelyd pan fu Hywel f. yn 950. Dilynodd rhyfel cartrefol a gorchfygwyd Ieuaf yn 969. Carcharwyd Iago yn ei dro yn 979 gan Hywel, mab Ieuaf, a daeth Hywel yn frenin Gwynedd. Iago yw'r unig Gymro y gellir bod yn weddol sicr ei fod gyda'r isbenaethiaid eraill a blygodd lin i Edgar, yng Nghaer, yn 973 — amgylchiad a ysbrydolodd yr hanes am siwrnai orchfygol Edgar ar Ddyfrdwy. Ni wyddys ym mha flwyddyn y bu f. Yn yr achau enwir mab iddo, Cystennin, eithr ni bu i hwnnw deulu.
