What a great find. I was not fully aware that the Amerindians held that many black slaves, this does not suprise me though. The Amerindins held and traded slaves long before the white man re-emerged on the North American continet.
DID YOU KNOW,,,, that when the Pilgrins showed up, shortly there after they passed laws stating that No indian or Black could hold "Christian" (read white) Slaves.
