Free Blacks on the Winchester City, Virginia Personal Property Tax Lists, 1789-1862. Joy MacDonald. 2013.
The author has continued her research into Winchester City, which was taxed separately from Frederick County (see above for full description).
In the case of Winchester, the author has abstracted the information for free African-Americans into seven categories:
occupation [only given infrequently on the rolls];
property description & value;
memo [oftentimes describing the exact location of the taxpayer or his former owners if freed in recent decades].
