The Vance family story begins hopefully in post-war America. J. D.'s grandparents were "dirt poor and in love," and moved north from Kentucky's Appalachia region to Ohio in the hopes of escaping the dreadful poverty around them. They raised a middle-class family, and eventually their grandchild (the author) would graduate from Yale Law School, a conventional marker of their success in achieving generational upward mobility.
But as the family saga of Hillbilly Elegy plays out, we learn that this is only the short, superficial version. Vance's grandparents, aunt, uncle, sister, and, most of all, his mother, struggled profoundly with the demands of their new middle-class life, and were never able to fully escape the legacy of abuse, alcoholism, poverty, and trauma so characteristic of their part of America. Vance piercingly shows how he himself still carries around the demons of their chaotic family history.
