It won't be tribes -- because by the time our ancestors were emancipated most were 2-3 generations deep. So, they would have been through so much -- and mixed with all different tribes and countries.
Remember, when they got here -- none of that tribe and African country stuff mattered. They became one with one another -- hence making our ethnic group.
Also, we will have so many ancestors - remember maternal and paternal side - so most will know by state and county.
For instance, the surname WARD and JACKSON is in my family - both out of Alabama. But, both surnames had multiple plantations in Alabama and in other states.
They started with the oldest WARD in - then he passed down more to his sons and they opened more plantations and so on...

One of his sons enslaved an arm of my family.
