“Whites even with no shadow of legal right to Negroes living among the Indians nevertheless frequently claimed and seized them. A case in point is that of the friendly chief Econchattemicco. A band of whites, taking advantage of the disturbed state of Florida on the eve and at the beginning of the Seminole War, descended on his settlement, seized the Negroes there, and carried them off to slavery in Georgia. Among those thus enslaved was the old chief's ‘Granddaughter (half Negro) stolen and carried away.’
“It is thus certain that even a very prominent chief did have a granddaughter, if not a daughter, who was part-Negro, and that this granddaughter was not immune from seizure and sale as a slave. It is even of some interest, though perhaps of little actual significance, in this connection, that Osceola is said to have been related to Econchattemicco, one of whose wives was allegedly a sister of Osceola.”
