George Samuel "Sam" Kirk is James Tiberius Kirk's older brother. James' senior by about 10 years, Sam followed the footsteps of their father, George Kirk Sr., by joining Starfleet. However, unlike his father and brother, who both went into command, Sam is a science officer specializing in life sciences.
Sam was the older brother of James T. Kirk, who was the one who gave Sam his nickname. When James was given command of the USS Enterprise, he, along with his family, were present when James left on his five-year mission. (TOS: "What Are Little Girls Made Of?")
Dan Jeannotte has finally brought the character of George Samuel Kirk to life on Star Trek: Strange New Worlds. The older brother of James T. Kirk (Paul Wesley), Sam works in the life sciences department on the USS Enterprise as a xenoanthropologist.
In the original Star Trek series, Captain Kirk's brother was named George Samuel Kirk. He was often referred to as "Sam." Sam Kirk made an appearance in the episode "Operation -- Annihilate!" where he was, unfortunately, found dead by Captain Kirk due to the attack of a parasitic creature.

What happened to Captain Kirk's brother Sam?
Sam makes one appearance in the Tos episode, "Operation - Annihilate!," where the elder, mustachioed Kirk is also played by William Shatner. Unfortunately, Sam was killed by flying alien parasites, and he is already dead when Jim finds his big brother.
In the 1950s he led research on early intervention for children with mental retardation. After his famous 1963 'learning disabilities' speech he was appointed by President John F. Kennedy to the post of Director of the Office of Education's Division of Handicapped Children for 1963 and 1964.
Sam Kirk's first and only appearance on the Original Series was in "Operation -- Annihilate!" In that appearance, Kirk discovers his brother and Sam's family perished on a Deneva colony. Portrayed by William Shatner, the only distinction between James and Sam was a magnificent mustache.
Captain, James T. Kirk, had an older brother, George Samual “Sam” Kirk, who was working on the planet, Deneva, until he died there (TOS, Operation-Annihilate). George Kirk had a wife, Aurelia, and three sons. James Kirk had no other brothers or sisters.
Kirk (William Shatner) and Dr. Carol Marcus (Bibi Besch) had a son who was an adult by 2285 could be answered by Star Trek: Strange New Worlds. David and Carol were the masterminds of Project Genesis, technology that could terraform dead worlds for the United Federation of Planets.
Carol Marcus. Played by Bibi Besch, Carol Marcus was introduced in Star Trek II: The Wrath of Khan as Kirk's estranged love and the mother of his son, David (Merritt Butrick). Kirk's mother has only been seen onscreen in J.J. Abrams' Star Trek (2009), where she was played by Jennifer Morrison.
Kirk's father, George, was himself a Starfleet officer and saw his son grow up to be a great officer in his own right. We just never saw him on screen in the Original Series. In the Kelvin timeline, aka the Abramsverse, George Kirk died saving an escaping crew from the Romulan vessel Narada.
Did James Kirk have a brother in the original series?
Sam Kirk only made one appearance in the Star Trek: The Original Series episode "Operation - Annihilate!", but he was already dead. Further, Sam's corpse was played by William Shatner wearing a fake mustache, and Jim's older brother wasn't truly established as an actual character.
(TOS: "The Deadly Years"; Star Trek IV: The Voyage Home; Star Trek V: The Final Frontier; ENT: "In a Mirror, Darkly, Part II" production resource; SNW: "Tomorrow and Tomorrow and Tomorrow") He was the son of George and Winona Kirk; their other son, his brother, was George Samuel.
Aurelan Kirk was a female Human civilian in the 23rd century. She was married to George Samuel Kirk and they had three sons, including Peter. Her brother-in-law was Captain James T. Kirk.
In canon, Captain James T Kirk only ever fathered two children. Both were human, and both children died. The first was Dr David Marcus, born to Dr Carol Marcus, a blonde lab technician at the time.
In order to demonstrate how close they truly were, and how much Kirk had “humanized” Spock, they would have him use the diminutive of James, which is Jim. This is a name used by those close to the Captain or in intimate moments of friendship.
Kirk wasn't noted as dead until Generations. Money. Gene Roddenberry tried to get anyone he could from TOS to do a cameo in the TNG pilot. William Shatner, Leonard Nimoy, Nichelle Nichols, James Doohan, Walter Koenig and George Takei all turned him down.
Jeannotte has a recurring role on Star Trek: Strange New Worlds as George Samuel “Sam” Kirk. The character was originally played by William Shatner himself—with a mustache—in the TOS episode “Operation — Annihilate!”
After Picard met Kirk, he remained as Captain of the USS Enterprise-E for another 14 years before he was promoted to Admiral (and subsequently quit Starfleet in protest) in 2385.
George Samuel "Sam" Kirk, Jr., the eldest son of Winona and George Samuel Kirk, Sr., and brother of James T. Kirk, was born on 12 August 2230. This character is a member of the Kirk family.
Samuel Kirk is recognized for his accomplishments in the field of special education, while sometimes being referred to as the “Father of Special Education”. He began his teaching career at the Oaks School in Chicago in 1929, where he worked specifically with boys who were delinquent and had mental disabilities.
Peter is kidnapped by the Klingon amabassador Kamarag who blames Capt. Kirk for the death of his favorite protege Kruge (but it was perfectly OK to him that Kruge killed Kirk's son David). Kamarag orders his niece (his sister's daughter) Valdyr to be Peter's jailer.
In Star Trek 2009 James Kirk is an only child (cut content not withstanding). In the prime timeline (primeline) James Kirk has an older brother, George "Sam" Kirk Jr. Since the timeline split happened basically as baby Kirk was being born, a lack of older brother cannot be attributed to it.
