Son of the late Jonathan and Anne Hodgins ("The Heiress in the Hill", season 9), Jack Hodgins is thought to have been an only child until he discovers in Season 9 that he has an older brother named Jeffrey, institutionalized with schizoaffective disorder. In "The Blonde in the Game", his uncle Preston is introduced. Hodgins' grandfather served as a "code-breaker" under Admiral Chester W. Nimitz during World War II. His family is the single largest donor to the Jeffersonian. In season 8, after serial killer Christopher Pelant hacks into Hodgins' savings and drains his bank accounts and the accounts of the entire Cantilever Group, he and Angela are forced to scrimp; yet, in season 9, he tells Dr. Sweets that he is content as he still has his work at the Jeffersonian and family—the two things which he values the most.
