On January 19, 1973, three days after officially divorcing Roger Vadim, Jane married antiwar activist and politician Tom Hayden in a casual ceremony at her home in LA. She was pregnant at the time, and that July, their son was born. Jane and Tom named their baby boy Troy O'Donovan Garity, after Viet Cong bomber Nguyen Van Troi and Irish revolutionary Jeremiah O'Donovan Rossa. They gave him his paternal grandmother's maiden name, Garity, as "Fonda and Hayden carried too much baggage."
