Ivar known in Old Norse as Ivarr Beinlauss possible meaning, bone-loose or bone-less. (Could it be that he suffered from brittle bone disease or was he simply double jointed or could he have been exceptionally tall and loose limbed). What ever his disability was, if it was indeed a disability, it certainly did not affect his mind. He was already the King of Dublin when he masterminded and led, along with his brothers, Halfdan and Ubbe the great Danish army that arrived in three to four hundred longships to land in East Anglia in 865.
