This is interesting. I've been trying to figure out a way to add people enslaved by my ancestors, in order to help others trace their families. In some cases, I have first names and sometimes relationships (before their freedom), but have had no mechanism which might be useful or helpful in figuring out how the family trees might have developed. It seems that another identifier might be workable, like slave-holding family/person name in place of LNAB for those before emancipation, or farm/manor/plantation name, or even county/state. Or all of the above, added as identifiers.
