... actually IS a descendant of Jefferson Davis?
It's the kind of assertion that, a) should be fairly easy to check, and b) should draw the attention of fact-checkers.
Yet I read the assertion repeated in dozens and dozens and hundreds of stories, and none went to far as to specify what relationship she really is (i.e., 'great-great-great-granddaughter on her mother's side, etc etc.').
Since it's the 'hook' many of the stories were built around, you'd think some editor somewhere would say to some reporter, "do we have any idea if this is really true?"
