Definition and stakes

Charles J. Archard The Portland Peerage Romance

His name in its extended form was William John Cavendish-Scott-Bentinck, and for many years, till the death of his brother Henry, he had no prospect of succeeding to the Dukedom. At nineteen he was a lieutenant in the army, and in 1824 was returned as Member of Parliament for King's Lynn; but the duties of a legislator do not seem to have been much to his taste and he resigned in 1826, his brother, Lord George Bentinck, being elected to take his place.
The fourth Duke kept a large stud of race-horses and Lord John was brought up in the atmosphere of the turf.
