North Benfleet belonged to Harold in the time of King Edward the Confessor and passed into the hands of William I after the Norman Conquest. There are two entries whieh relate to South Benfleet, although it must be admitted that the actual identification of the Benfleet manors mentioned in Domesday Book is by no means complete. One of these entries records that King William gave the church at South Benfleet with seven hides (a hide is generally regarded as about 120 acres) and thirty acres, which had all formerly belonged to the Abbey of Barking, to St. Peter of Westminster (Westminster Abbey). In the time of Edward there were two ploughteams on the demesne and five belonging to the "men," there were 15 villeins (unfree cultivators) and seven bordars (unfree cultivators of a lower status), and pasture for 200 sheep.

There were then fifty sheep and five swine. Half the profits of a mill monopoly also went to the manor, and it is recorded that an eighth hide which had also belonged to St. Mary of Barking had been given by Ingelric to St. Martin (? S. Martin's le Grand) without the King's sanction. The Abbey at Barking was one of the richest and most famous of the early Benedictine houses; it was founded about 675 by Erkenwald, third bishop of London, whose sister Ethelburga was the first abbess. Westminster Abbey, it is interesting to note, also obtained considerable grants of land in North Benfleet. The other entry records that a certain free man, Alwine (of whose fate nothing is known), held in King Edward's time a manor of two hides at Benfleet, but at the time of the Survey this was held by Sweyn. In King Edward's time there were three ploughteams on the demesne, but at the time of the Survey there was only one, although it was noted that another ploughteam could be employed. There were five 10
