I think that all editors have some personal investment in every story they run. It doesn’t matter how calculating, even cynical, the impetus for the article may have been: Once it’s printed and cast out to the wide world, the editor lives in a perpetual cringe against any number of challenges that all boil down to “Who asked?”

But, in this case, I have an especially personal interest in a piece. Jillian Sim’s article about her investigation into her past is a tale any reader should find compelling, suggesting as it does the mysteries and riches concealed in everyone’s personal past.

This particular story, however, is by my step-daughter.

I helped raise Julian from the time she was two years old. She was a delightful charge—straw-haired, blue-eyed, lively, and agreeable to most uses of the adult world. She cheerfully absorbed my pieties about table manners and street crossings, was good company on the long, sticky car trips of childhood, even acquiesced happily in visits to historical sites (although once, when she was nine, at Henry Ford’s vast and wonderful Greenfield Village, I did hear her mutter to her older brother, “He’s going to make us look at another goddamn sawmill!”). I was just as surprised as she was when the dimensions of her history began to reveal themselves.

It’s been said that race is not just an important part of the American admixture; it is the important part. This idea is succinctly encapsulated in the national attention paid the results of the DNA tests that recently ratified what overwhelming circumstantial evidence and common sense should have made manifest: Thomas Jefferson and his slave Sally Hemings were lovers and parents. Jefferson’s black descendants knew this; his white chose not to. (Not all of them: Lucian Truscott’s highly personal meditation on the largest meanings of the DNA business suggests the vigor with which he has campaigned to bring Jefferson’s African-American descendants to the fore.)

I suspect Jill’s story will be more surprising to our white readers than our black ones. Indeed, it may be far less surprising a decade down the road. As Cyndi Howells points out in her story, the internet has opened our past in ways that would have been unimaginable as recently as a decade ago. Go look up your name, and see what may be waiting for you.

I probably wouldn’t have the job I do if I weren’t an optimist about America, but I strongly believe that the fact that Jill was exhilarated rather than chagrined by what she discovered says something about the way we have come in little more than a generation, despite the path’s still being a steep one. So, too, does the attitude at Jefferson’s home. When, in 1972, American Heritage first published the results of Fawn Brodie’s scrupulous research into the relationship, Carla Davidson, then a picture editor, asked the curator at Monticello if he had a portrait of Sally Hemings. “No, young lady; I don’t,” said this custodian of our heritage, “and if I
