HUNDRED a military and administrative district, dating to the 10th C. under King Aethelred, but in use as late as the 17th C., in early British colonial America. A hundred is not 100 acres but 100 hides, one of which will support a family of that day. Each hide varied from 60 to 120 acres depending on the quality of the land . Famous American hundreds were Bermuda Hundred, and Martin's Hundred which had at least 21,500 acres in the first settlement and 200 settlers.
