Summary

• Captain James T. Kirk's father, George Samuel Kirk, was a dedicated and accomplished Starfleet officer who prioritized his career over his family's needs.
• In the Kelvin Timeline, Lieutenant George Kirk heroically sacrificed his life to save others during a confrontation with Captain Nero's Romulan ship.
• Lt. Sam Kirk, James' older brother, appeared in Star Trek: Strange New Worlds as a xenoanthropologist who faced personal insecurities and fear but still stepped up to help in dangerous situations.

Throughout the Star Trek franchise, there have been three different George Samuel Kirks, the name held by both the father and brother of Captain James T. Kirk (William Shatner/Chris Pine/Paul Wesley). Since his introduction in Star Trek: The Original Series, Captain Kirk has become one of the most iconic characters in all of science fiction. Due to the nature of television in the 1960s, most episodes of TOS told standalone stories. Because of this, not much information was shared about Kirk's past or his family unless it directly related to the story of the week.
The first George Samuel Kirk was the father of James T. Kirk and Samuel Kirk, and was not officially introduced until J.J. Abrams' Star Trek (2009), as portrayed by Chris Hemsworth. Named after his father, Samuel Kirk (Dan Jeannotte) did not become a fully realized character until Star Trek: Strange New Worlds, where he serves on the USS Enterprise commanded by Captain Christopher Pike (Anson Mount). The current television tradition of more serialized storytelling and more focus on franchise canon has allowed modern Star Trek films and television shows to dive deeper into the backstories and family histories of the characters.
