Courtney Kelly was a hunter and a member of Duncan McKann's failed expedition to track down ghouls from the Valley Galleria. Jacqueline and Courtney were wounded early on, left under the care of Hardball to recuperate. Apparently, the Mr Gutsy was a poor medic, as both of them died. Before she perished, Courtney left behind a will, asking the founder to find a home for her two cats.
Courtney Kelly appears only in Fallout 76.
