He rose to the rank of colonel in the army in 1745, and twenty-seven years later was promoted General; but it does not appear that he saw any service.

The second Duke of Kingston will, however, always be remembered for his marriage in 1769 with the beautiful and notorious Elizabeth Chudleigh, who was nine years his junior.

She had in 1744 married secretly Augustus John Hervey, afterwards sixth Earl of Bristol, who survived until December, 1779.

She had long been living with the Duke, but in 1769 she obtained a divorce _a mensa et thoro_, which she believed erroneously annulled the marriage.

The Duke died in 1773, when all his titles became extinct.
