Bastard is a famous English surname of 11th century Norman-French origin. William the Conqueror, the former Duke of Normandy, was known as William the Bastard, and the original Bastards may well have been closely associated with him. Initially, and for several centuries, "bastard" was not considered a term of abuse; rather it marked the status of a natural off-spring within a noble family. The surname has been carried by the Bastard family of Kitley House, Devon, for at least seven centuries. The first known record of the surname anywhere in the world is thought to be for Robert Bastard of Devon in the Domesday Book in 1086.
Bouchier is a surname of early French origins, introduced to England by the Normans after the 1066 Conquest. The first recorded spelling of the family name is Ailwardus le Bochere, in 1184, in the Pipe Rolls of London.
