Hello All,
Searching for FPOC's in Ohio, the Miami Valley in particular? Try the site shown below, especially the Miami County Page, there you will find an abstract of FPOC Head of Household from the 1850 Federal Census.
Included in this abstract are many of the former slaves of John Randolph of Virginia whose Will freed 380+ individuals in one (1) action. (1846)
Notice the lack of 'Randolph' surnamed folks. Another issue, what surnames names did former slaves take and why?
