From Wikipedia: The names of Gunnor's parents are unknown, but Robert of Torigni wrote that her father was a forester from the Pays de Caux and according to Dudo of Saint-Quentin she was of noble Danish origin.[3] Gunnor was probably born c. 950.[2] Her family held sway in western Normandy and Gunnor herself was said to be very wealthy.[4] Her marriage to Richard I was of great political importance, both to her husband[a] and her progeny.[5] Her brother, Herfast de Crepon, was progenitor of a great Norman family.[4] Her sisters and nieces[b] married some of the most important nobles in Normandy.[6] Robert of Torigni recounts a story of how Richard met Gunnor.[7] She was living with her sister Seinfreda, the wife of a local forester, when Richard, hunting nearby, heard of the beauty of the forester's wife. He is said to have ordered Seinfreda to come to his bed, but the lady substituted her unmarried sister, Gunnor. Richard, it is said, was pleased that by this subterfuge he had been saved from committing adultery and together they had three sons and three daughters.[c][8] Unlike other territorial rulers, the Normans recognized marriage by cohabitation or more danico. But when Richard was prevented from nominating their son Robert to be Archbishop of Rouen, the two were married, "according to the Christian custom", making their children legitimate in the eyes of the church.[
