Jenny Slew was born about 1719 as the child of a free white woman and a black slave. She lived her life as a free woman until 1762 when she was kidnapped and enslaved by John Whipple. Jenny Slew is believed to be the first person held as a slave to be granted freedom through trial by jury. In November of 1766 the jury ruled in favor of the plaintiff and ordered Whipple to free Jenny Slew. She was awarded £4 in damages and £5 in costs.
