Larger baronial estates.
Cornelius J. Moynihan & Sheldon F. Kurtz, Introduction to the Law of Real Property 3 (4th ed. 2005):
The larger baronial estates, or honours as they came to be called, were normally created out of the holdings of numerous Englishmen. As many as eighty English estates, situated in different regions, might be combined to compose a single lord’s honour. In the course of the Norman settlement several thousand smaller estates were compressed into fewer than two hundred major honours. The lords of these honours were the men who, with William, established the new English state.
