...there's hardly an Indian that doesn't have some African-American ancestors.

The freed blacks were semi-pariahs in the Northeast right after the Revolution, and when not in cities were to be found on marginal land, on the fringes of farming communities -- right where the surviving Indians were. Intermarriage was extremely common

SE Massachusetts, Rhode Island, Connecticut, Long Island -- all places where there's usually a 'joke' about the local Moneg Indian tribe -- 'Moneg' for 'Mostly Negro'.

Racism against blacks, not Indians, held up tribal recognition for several bands in New England.
