In doing genealogy you start with yourself and work your way back. This is how I got to Edward Woody. I have all of Williams children as there were 15 of them, I have their marriages, there children their deaths etc...but nothing that yields any information about Edward.
William Draper my GGG-Grandfather was at some point I assume a slave. In 1866 when given the permission to co-habitate he did so under the name of Draper (even though his last owner was Robert Via). In 1870 he went by the name Via although he was free. Finally in 1880 he began using the name Draper again. So like with any family of color (mine being mulatto) as Williams wife was an indentured servant I dont know if Edward was free, was WOODY his name or a name taken on from a slave owner...again records on people of color are DIFFICULT to trace.
Unless you are DR. Louise Gates (WHO DO YOU THINK YOU ARE) I dont think ANY family of color (or multi-race) will ever truly find and trace their lineage.
