John Moore bought it from Charles Mercer in 1835, and Moore descendants kept the waterwheels turning until 1971 - 136 unbroken years of one family grinding the wheat and corn of the Loudoun Piedmont. The mill itself is older than that. Built between 1807 and 1809 on the Little River by an indentured worker named William Cooke, it sits at the edge of the Aldie village that grew up around it. Cooke worked four years to build the mill in exchange for a half share of the operation. He sold his half back to Mercer in 1816. The Moores took it over almost twenty years later. They were still there when the cars started coming.
