Borden is a village and electoral ward situated immediately south west of Sittingbourne, Kent, from which it is separated by a small area of rural land. The history of the name could be questioned. It may be derived from bor (hill) and then either from denu (valley) or denn (woodland pasture). It may also derive from "boar" "den", as it was known that the wild animals were found in the surrounding areas. Borden was first recorded in the twelfth century as Bordena. However it is more likely to stem from Sir Francis de Bourdon,(variations today also include Borden/Burden/Bourdon) who descended from the de Bourdons of Bayeux, in Normandy, France. Francis de Bourdon became Lord of the existing castle and surrounding lands, granted to him by William the Conqueror, as a gift to his vassal after the great Norman victory in 1066, and at which time became known as Bourdon. The lands were previously lorded over by the Saxon Ethelwolf of Kent, who perished at the Battle of Hastings (1066), Over the next few generations the name had become more English to reflect the Saxon population and became known as Borden.
