If you want to go outside the box, there’s Robert Carter, the richest of the Virigina landowners, who simply released his 500 slaves from bondage while Jefferson was writing pretty things and banging Sally Hemings.
In his essay “The Anti-Jefferson,” Andrew Levy concludes:
The more one reads in the 21st century about a man like Robert Carter, the more one feels a sense of fury and frustration that there were already men and women in the 1790s prepared to surrender money and power to bring a dull end to the institution of slavery, that the whole thing — the Civil War, Jim Crow, the Ku Klux Klan, 200 years of relentless bitterness and division — could have whimpered and died in the Potomac tidewater. It is infuriating to consider this alternate history, in which Robert Carter is the founding father of the only American Revolution we truly lost. It is even more infuriating, however, to consider that we have been unable to find a single use for him. He does not sooth us, excuse us, or help us explain ourselves. But what is most incriminating is that Robert Carter does not even interest us, because that forces us to consider whether there now exist similar men and women, whose plain solutions to our national problems we find similarly boring, and whom we gladly ignore in exchange for the livelier fantasy of our heroic ambivalence.
