Answer by taking a quote from the following article:

William Randolph Hearst Sr. (; April 29, 1863 - August 14, 1951) was an American businessman, politician, and newspaper publisher who built the nation's largest newspaper chain and media company Hearst Communications and whose flamboyant methods of yellow journalism influenced the nation's popular media by emphasizing sensationalism and human interest stories. Hearst entered the publishing business in 1887 after being given control of The San Francisco Examiner by his wealthy father.

William R. Hearst was born in San Francisco, to millionaire mining engineer, goldmine owner and U.S. senator (1886-91) George Hearst and his wife Phoebe Apperson Hearst.  His paternal great-grandfather was John Hearst, of Ulster Protestant origin. John Hearst migrated to America from Ballybay, County Monaghan as part of the Cahans Exodus with his wife and six children in 1766 and settled in South Carolina. Their immigration to South Carolina was spurred in part by the colonial government's policy that encouraged the immigration of Irish Protestants. The names "John Hearse" and "John Hearse Jr." appear on the council records of October 26, 1766, being credited with meriting 400 and 100 acres (1.62 and 0.40 km2) of land on the Long Canes (in what became Abbeville District), based upon 100 acres (0.40 km2) to heads of household and 50 acres (20 ha) for each dependent of a Protestant immigrant. The "Hearse" spelling of the family name never was used afterward by the family members themselves, or any family of any size. A separate theory purports that one branch of a "Hurst" family of Virginia (originally from Plymouth Colony) moved to South Carolina at about the same time and changed the spelling of its surname of over a century to that of the immigrant Hearsts. Hearst's mother, nee Phoebe Elizabeth Apperson, was also of Irish ancestry; her family came from Galway. She was the first woman regent of University of California, Berkeley, funded many anthropological expeditions and founded the Phoebe A. Hearst Museum of Anthropology.  Following preparation at St. Paul's School in Concord, New Hampshire, Hearst enrolled in the Harvard College class of 1885. While there he was a member of Delta Kappa Epsilon, the A.D. Club (a Harvard Final club), the Hasty Pudding Theatricals, and of the Lampoon before being expelled for antics ranging from sponsoring massive beer parties in Harvard Square to sending pudding pots used as chamber pots to his professors (their images were depicted within the bowls).
