The manor was held by Geoffrey de Mandeville in 1086, and by Esger in the time of the Confessor. Before the Conquest it had been assessed at 30 hides, but it only counted for 10 by 1086. As well as the ploughland there were 5 acres of meadow and woodland for 40 pigs. The recorded population of 23 villans, 12 bordars and 3 slaves probably represents a total of more than 150. No church was noted, but there were two mills.
Before the middle of the 12thc the manor passed to the family of London of Kidwelly in Wales, and Maurice de London was in possession of bothe Kidwelly and East Garston by 1141. It descended with that family until the end of the 12thc, the male line failing shortly thereafter. A charter of Maurice de London granted the church to the monastery he fouded at Ewenny (Glamorgan), but the advowson remained with the lords of the manor.
