As detailed in "The Marvel Saga: Official History of The Marvel Universe #16", Susan Storm, and her younger brother, Jonathan grew up in the town of Glenville, Long Island, children of a physician named Franklin Storm and a woman named Mary. The parents left their kids alone one night to travel to a dinner honoring Dr. Storm. On the way, a tire blew out but only Mary was injured. Franklin escaped injury and insisted on operating on his wife. He was unable to save her and she died. After his wife's death, Dr. Franklin Storm became a gambler and a drunk, losing his medical practice, which led him to the accidental killing of a loan shark. Franklin did not defend himself in court, because he still felt guilty over Mary's death. With their father in prison, Susan had to become a mother figure for her younger brother.
