The name Bygrave is a toponymic, surname, which is derived from nearby geographical features. It has Anglo-Saxon origins and arising in Hertfordshire were it is most likely they held lands and a family seat at Bygrave. Originally the surname was derived from the Old English word biggrafau which meant dweller by the ditch. There are records of a Leommaer Bygrave prior to the Norman Conquest (circe 1015) and the family still held the land at the taking of the Domesday Book - the land consisted of a village and a mill from the Bishop of Chester.

Current research identifies the earliest known ancestor of our Bygrave line as being Robert Bygrave of Sandon in Hertfordshire in the mid 1500s. My branch of the family finds itself in the West Indies in the late 1700s. Robert's 5 great granddaughter Jane Bygrave emigrates to Australia in 1853.
