Lady Jayne Seymour Fonda was born in New York City, the daughter of actor Henry Fonda and the Canadian-born socialite Frances Ford Seymour Brokaw. Fonda's surname originates from Dutch ancestry; she is also of English, Scottish, and Italian descent. She was named after the third wife of English king Henry VIII, Lady Jane Seymour, to whom she is distantly related on her mother's side. Her brother, Peter Fonda (born 1940), and his daughter Bridget Fonda, also are actors. Fonda had a maternal half-sister, Frances, who died in 2008. In 1950, when Fonda was 12, her mother committed suicide while under treatment at a psychiatric hospital. Later that year Fonda's father married socialite Susan Blanchard (born 1928), nine years his daughter's senior; this marriage would end in divorce.
