Ēomǣr

Eomer / Ēomǣr
According to the Anglo-Saxon Chronicle, he was the great-great-grandfather of Creoda 1st King of Mercia. He is considered the ancestral patriarch to the Kings of Mercia.
Eomer himself was the son of Angeltheow (Offa of Angel).
Eomer's son was Icel.

He is mentioned in lines 1958 thru 1963 of the Anglo-Saxon Epic of Beowulf as the son of Offa of Angel and grandson of Garmund.

"...forþam Offa wæs geofum and guðum gar-cene man, wide geweorðod; wisdome heold eðel sinne, þonon Eomær woc hæleðum to helpe, Heminges mæg, nefa Garmundes, niða cræftig."

"...Hence Offa was praised for his fighting and feeing by far-off men, the spear-bold warrior; wisely he ruled over his empire. Eomer woke to him, help of heroes, Hemming's kinsman, Grandson of Garmund, grim in war."
(Gummere's translation)
