Ælfgar, Earl of Mercia

Ælfgar (died 1062) was son of Leofric, Earl of Mercia, possibly by his well-known wife Godgifu (Godiva), although more probably by an earlier marriage. He succeeded to his father's title and responsibilities on the latter's death on August 31, 1057. Ælfgar is best known for his alliance 1055-1062 (political and marital) with the Welsh prince Gruyffd made after he was banished and declared outlaw. The Welsh prince and his Mercian ally successfully invaded Hereford, and sacked the town and castle in 1055. Ælfgar was restored to his rights after a second invasion.

Ælfgar was succeeded as Earl of Mercia by his eldest son, Edwin. His second son, Morcar was elected Earl of Northumbria when Tostig Godwinson was ejected by the Northumbrians.

His daughter, Edith (or Aldgyth) married firstly the Welsh prince Gruffyd (kd. 1063), and secondly 1066 Harold Godwinson (kd 1066 Hastings). She had issue by both husbands.

Ælfgar is said by some to be related to Hereward the Wake, son of Leofric of Bourne, but the connection if any is not proven.
