Actually, the “Dusky Sally” relationship was less scandalous to those who knew of both relationships than Jefferson’s adulterous relationship with Maria* Cosway, a beautiful but married artist he met in Paris. (She was the Italian reared daughter of English parents and her husband, Richard, who was probably homosexual, was an English painter at the court of Louis XVI.) There is some evidence that he tried to get her to leave her husband for him, but she would not; they remained close friends until Jefferson’s death, though they didn’t see each other in person for the last thirty years of his life.
(There was also a highly embellished account of Jefferson’s attempts as a young bachelor to seduce Betsy Walker, the wife of a family friend; Jefferson acknowledged forty years later that the incident happened, but the fact that he remained friends with both the woman and the husband would imply it wasn’t as serious or as crass as the journalist Callendar [who also “broke” the Hemings story] painted it.)
For a really interesting story of miscegenation in Virginia, check out the accounts of the murder trial of George Wythe Sweeney. He was the grandnephew of George Wythe, the judge and law professor who had been mentor to Jefferson and James Madison. Unlike most Virginia aristocrats Wythe had serious money (i.e. he wasn’t mortgaged up to his eyeballs like Jefferson and Madison) and he wanted to leave a large share of it to Michael Brown, a young well educated free mulatto who was almost certainly Wythe’s son. (Wythe freed all of his slaves upon the death of his wife; Brown’s mother was his cook, Lydia Broadnax, one of the slaves he freed and to whom he left a house and grounds- almost unheard of thing for a white man to do.)
Wythe had no children by his two dead wives and Brown, born when he was 60, was regardless of his paternity and race definitely regarded as a son to the old man. Unfortunately Wythe had a 19 year old grandnephew, G.W. Sweeney, who saw himself as his uncle’s rightful heir, who didn’t want to share the inheritance, and who knew that Wythe’s will said in the event of the deaths of Broadnax and Brown that Sweeney was to inherit their portions. Plus, Sweeney needed money- he was a chronic gambler, had forged several checks on his uncle’s accounts that he needed to make good, and was just a generally evil fellow.
Long story short- he poisoned his 80 year old uncle, the former-slave Broadnax, and the 20 year old lightstkinned heir-to-be Michael Brown (who, again, was probably Wythe’s biological son). He was seen putting the poison in their food by Broadnax (he told her it was spices). Ironically it was the youngest and healthiest of the three, Michael Brown, who died of the poisoning. Lydia recovered and Wythe came too enough to change his will- completely disinheriting his nephew- before dying himself (extremely distraught over the death of Brown).
Why this is relevant: Sweeney came to trial for poison. White men who had overheard the tale of the poisoning from Lydia Broadnax were allowed to testify, but Lydia herself, the sole EYEWITNESS to the murders, was not- black people, even if light skinned and free (she was both) were not allowed to testify against whites, and besides which Wythe was a pariah for leaving her and her light-skinned son a large portion of his considerable property. Sweeney was acquitted. (There was a little justice: even if he wasn’t convicted everybody still knew he was a murderer, plus he received nothing from the estate so he was reduced to poverty.)
The executor of Wythe’s estate and the man whom he personally asked to oversee hte completion of his young mulatto heir’s education was Thomas Jefferson, his friend and at that time the president of the U.S. who was in the midst of a major scandal over his own alleged interracial relationship. It’d be a cool novel, cause while it’s impossible to speculate what Jefferson thought, it could be well fictionalized.
