Ingwær
Ingwær (also referred to as Ingvar, Ivar or Ivarr; ) was a Norse King of Northumbria. According to Æthelweard's Chronicon he was a co-king of Northumbria along with his brothers Eowils and Halfdan, though the Anglo-Saxon Chronicle does not mention him. By Æthelweard's account he died at the Battle of Tettenhall alongside his brothers in 910.
