His paternal great-grandfather was John Hearst of Ulster Protestant origin. John Hearst, with his wife and six children, migrated to America from Ballybay, County Monaghan, Ireland, as part of the Cahans Exodus in 1766. The family settled in the Province of South Carolina. Their immigration there was spurred in part by the colonial government's policy that encouraged the immigration of Irish Protestants, many of Scots origin. The names "John Hearse" and "John Hearse Jr." appear on the council records of October 26, 1766, being credited with meriting of land on the Long Canes in what became Abbeville District, based upon to heads of household and for each dependent of a Protestant immigrant; the "Hearse" spelling of the family name was never used afterward by the family members themselves, nor any family of any size. Hearst's mother, née Phoebe Elizabeth Apperson, was also of Scots-Irish ancestry; her family came from Galway. She was appointed as the first woman Regent of University of California, Berkeley, donated funds to establish libraries at several universities, funded many anthropological expeditions, and founded the Phoebe A. Hearst Museum of Anthropology.
