She was born in the Suarez System, as was her husband, Russell Bellefeuille. Both detested the Committee of Public Safety, but decided to make a living in the People's Republic nonetheless, raising two children, Diana and Matthew. By 1920 PD, Bellefeuille had reached the rank of Rear Admiral and served as the commanding officer of the Chantilly System picket. Her flagship was RHNS Cyrus. Her husband and children visited her in 1920 PD, when Chantilly was probed by the Royal Manticoran Navy as part of Operation Cuttworm II.
