What is "morcar"

Morcar (or Morkere) (died after 1087) was the son of Ælfgār (earl of Mercia) and brother of Ēadwine. He was the earl of Northumbria from 1065 to 1066, when he was replaced by William the Conqueror with Copsi.

Morcar (or Morkere) (died 1015) was a thane (minister) of King Æthelred the Unready. He was given lands in Derbyshire in 1009 including Weston-on-Trent, Crich and Smalley by King Æthelred, 1011 and 1012. He was also given the freedom from the three common burdens. He and his brother were executed in 1015. Morcar's brother's wife was later married to King Edmund Ironside.
