William Ancrum (c. 1722—February 24, 1808) was a wealthy American merchant, slave trader and indigo planter from Charleston, South Carolina who served in the Third General Assembly during the Revolutionary War (1779—1780).

[1] This collection provides insight into the economic impact of the American Revolution on Charleston planters and merchants, from the prices of slaves to restrictions on imports and exports.

When the citizens of South Carolina entered resolutions demanding their equal treatment as colonists in 1774, Ancrum was elected to serve as a representative for St. Matthew's Parish on the newly formed Committee of Ninety-Nine.

[7] In May 1780, when Charleston fell under British control, Ancrum signed a congratulatory address to Henry Clinton, an act which subsequently resulted in his being designated a Loyalist.

This, in conjunction with his service to the Crown on a committee to evaluate paper currency each month, led to his property being confiscated and his banishment from Charleston.

[4] While in London, Ancrum successfully petitioned the South Carolina State Legislature to lift the confiscation order and grant him twelve percent amercement.
