Possibly means
"bee wolf" (in effect equal to "bear") from Old English
beo "bee" and
wulf "wolf". Alternatively, the first element may be
beadu "battle". This is the name of the main character in the anonymous 8th-century epic poem
Beowulf. Set in Denmark, the poem tells how he slays the monster Grendel and its mother at the request of King
Hroðgar. After this Beowulf becomes the king of the Geats. The conclusion of the poem tells how Beowulf, in his old age, slays a dragon but is himself mortally wounded in the act.
