If it's that far back, you wouldn't have had one.

Effectively, African tribal relationships absolutely vanished in the Americas. Any sort of tribal lineage would have been lost. From that point on, it's an argument about becoming an "American Nation". I've previously talked about how the book "The Might of Nations" works to define what a Nation is as a political science concept. The American Revolution was filled with a lot of emphasis on building a "new nation of people", rather than simply a state. The nation of "Americans" were born out of the idea of "Liberty" by asserting that English Rights were universal within Liberal philosophy, and were entirely removed from the state and the monarchy. That these literally inalienable (inseparable) freedoms were bestowed upon the people themselves by God. Not bestowed as privileges and protections to subjects of a monarchy.

The basis of The American Experiment is about whether or not it is even possible to 'sink all differences and distinctions' into a name that represents new nation of people, dedicated to the idea of individual human liberty itself.

To throw all that away to claim affiliation with a people who do not know you, would not recognize you, who do not speak your language, and who's culture and values you do not share because some charlatan claimed that you had some sort of ancestral claim to their history (rather than your own) seems like an incredible waste.
