Kurt Vonnegut had seven children: he shared three with his first wife, adopted his sister Alice's three children when she died of cancer, and adopted another child, Lily. Two of these children have published books, including his only biological son, Mark Vonnegut, who wrote The Eden Express: A Memoir of Insanity, about his experiences in the late 1960s and his major psychotic breakdown and recovery; the tendency to insanity he acknowledged may be partly hereditary, influencing him to take up the study of medicine and orthomolecular psychiatry. Mark was named after Mark Twain, whom Vonnegut considered an American saint, and to whom he bears some resemblance, in both style and appearance.

His daughter Edith Vonnegut, an artist, has also had her work published in a book entitled Domestic Goddesses. Edith was once married to Geraldo Rivera. She was named after Kurt Vonnegut's mother, Edith Lieber. His youngest daughter is Nanette, named after Nanette Schnull, Vonnegut's paternal grandmother.
