Ildulb mac Causantín, anglicised as Indulf or Indulph,[1] nicknamed An Ionsaighthigh, "the Aggressor"[2] (died 962) was king of Alba from 954 to 962. He was the son of Constantine II; his mother may have been a daughter of Earl Eadulf I of Bernicia, who was an exile in Scotland.[3]
- ^ "Ildulb" is an Old Irish name derived from either the Old Norse name Hildulfr or the Old English name Eadwulf. It occurs in various contemporary Gaelic forms, such as Iondolbh, found in the Duan Albanach. The Latin Chronicle of the Kings of Alba uses Indolf and Idulfus. "Ildulb" was later rendered "Indulf" under Old French influence. Ildulb is used because by some historians because it correctly represents the name Hildulfr in Gaelic orthography; Eadwulf would perhaps be Idulb, hence that form is also used sometimes. The name never came into wider use in the Scottish world, or the Gaelic world more generally, and has no modern form. Walker, p. 97.

- ^ It is known a sister of Indulf married Olaf III Guthfrithson (Amlaíb mac Gofraidh) of the Uí Ímair and one of Indulf's sons was named Amlaíb. Walker suggests that Indulf's mother may have been a daughter of Earl Eadwulf, who was an exile in Alba. Eadwulf is rendered Ettulb in the Annals of Ulster, s.a. 913, where his death is reported.
