Sidney Painter (Studies in the History of the English Feudal Barony) did a
[preliminary] study of baronial incomes between 1160 and 1320 (chapter VII).
Of fifty-four barons he tallied figures for during a part of that period, Roger
de Lacy, constable of Chester, had the highest income in England at his death
in 1211 (800 pounds per annum). Next was William, Earl of Gloucester at 700
pounds, Robert, Earl of Leicester, at 560 pounds, and then Earl William de
Mandeville at 504 pounds per annum. So this would explain, in part, why John
de Lacy was vaulted to the peerage when the opportunity presented itself
without much dispute. The palatine Earl of Chester only had an annual income
of 327 pounds per annum in Henry II's reign.
