Sparsholt comprised three manors held by three freemen in 1066. They were combined into one under Froger the Sheriff, and in 1086 it was held by the king in demesne. Henry I granted it with Aldermaston and other manors to Robert Achard, and it passed to his son and grandson (both Williams) and remained in the same line throughout the Middle Ages.
In 1086 the royal manor included a church held with one hide by Edred the priest, and this also passed to Robert Achard.
