Actually the Freedmen's Bureau field office records contain a number of unique registers that are similar to the one you described. Herbert Gutman analyzed several black Virginia population records, but there were others, various lists of freedmen that served a number of purposes. Some of the details in these records are amazing, especially when parents account for all of their children, living, dead or lost. Perhaps you could post this to a genealogy list. I'm sure someone out there would take on the trascription project. To subscribe, change options, or unsubscribe, please see the instructions at http://listlva.lib.va.us/archives/va-hist.html
