(John). “A prodigious hand at matrimony, divinity, a song, and a peck.” He marries seven wives, loses all in the flower of their age, is inconsolable for two or three days, then resigns himself to the decrees of Providence, and marries again. (The Life and Opinions of John Buncle, Esq., by Thomas Amory.)
“John is a kind of innocent Henry VIII. of private life.” —Leigh Hunt.
