de Valognes (Valoignes, Valoines, Valoins, Valons, Valeynes, Valeignes, Valens, Valence, Valance, Valang, Valoniis) is a family name of two distinct powerful families with notable descendants in the centuries immediately following the Norman Conquest. Although a connection between them has been inferred by some authorities,[1] this is not supported by positive evidence.
The family descending from the Domesday ancestor Peter de Valognes is believed to have originated in Valognes (Valoniis in 1056 - 1066 ; Valuignes, Valoignes ab. 1175), in the Cotentin peninsula in Normandy. The family descending from Hamo de Valoines of Parham may have originated from Valaines in the region of Rennes in Brittany.[2]
