ÆLFGIFU OF NORTHAMPTON (c.990-1040) was the first QUEEN CONSORT of KING CANUTE OF ENGLAND AND DENMARK from 1030-1035. She was the mother of SWEYN KNUTSSON, KING OF NORWAY and HAROLD HAREFOOT, KING OF ENGLAND. Ælfgifu and Canute were not divorced before he married Emma of Normandy, and there is a lot of confusion over her exact status and the nature of her marriage. She served as regent from 1030-35, but was so unpopular that there was a revolt. HOUSE OF DENMARK.
