Thank you Deborah, Mike, and Rachel for all of the links and recommendations.  Coming to The Table, Enslaved.org and The Beyond Kin Project all look like a fabulous organizations and resources. You all have given me a good starting point. Where this will take me, I do not know, but the import of this type of research has never been clearer.
