Peter Kirk

Peter Kirk, was the eldest son of George Samuel Kirk Jr. and Aurelan Kirk, and resided on the planet Deneva with his family. In 2266, neural parasites struck Deneva, and killed his father. Peter and his mother were rescued by his uncle, James T. Kirk and the USS Enterprise (NCC-1701), although his mother died in sickbay. (TOS episode: Operation: Annihilate!).

Unlike his brothers Alexander Kirk and Julius Kirk, who were on Rigel IV when the neural parasites struck, Peter is taken to Starbase 10 by the Enterprise, and later returns to Earth to live with his grandmother, Winona Kirk. (TOS novel: The Last Roundup).
