Joanna McCoy

Joanna McCoy was the daughter of Leonard McCoy and Jocelyn McCoy

As a student, Joanna was on Cerberus II, c. 2260, when the crops failed. Carter Winston was instrumental in saving the colony and Leonard McCoy would express his gratitude to Winston personally (or so McCoy thought) in 2269.
