Jack Ketch

The manor of Tyburn was formerly held by Richard Jaquett, where felons for a long time were executed; from whence we have Jack Ketch.

[Monmouth] then accosted John Ketch, the executioner, a wretch who had butchered many brave and noble victims, and whose name has, during a century and a half, been vulgarly given to all who have succeeded him in his odious office.
