Æthelweard, king of the Hwicce

Æðelweard, King of Hwicce, apparently jointly with his presumed brothers Æthelheard, Æthelberht, and Æthelric. He was the son of Oshere.
He is known from charters:
In 692, together with Æthelheard, issued a charter to Abbess Cuthswith [1], and also witnessed a charter of Æthelred, King of Mercia [2], together with Æthelheard, Æthelberht, and Æthelric. In 693 the four brothers witnessed a charter issued by their father Oshere [3].
In 706 he granted land to Bishop Ecgwine [4]. In this charter Æthelweard is styled subregulus, Osheri quondam regis Wicciorum filius.
Possibly he is also the Æþeluuard dux who in 716 or 717 witnessed a charter issued by Æthelbald, King of Mercia [5].
