In 2268, Dr. McCoy was diagnosed with xenopolycythemia. He believed himself to only have a year to live, which he told Captain James T. Kirk, asking him to keep this news to himself.
No one thinks the HatfieldMcCoy feud was fully caused by this condition, but some people think the McCoy family's infamous temperament was partly caused by the fact that multiple family members had von Hippel-Lindau (VHL) disease. The disease is caused by a mutation of the VHL gene, which is a tumor suppressor gene.
McCoy later married Natira, the priestess of Yonada, as recounted in the episode "For the World Is Hollow and I Have Touched the Sky". In 2266, McCoy was posted as chief medical officer of the USS Enterprise under Captain James T. Kirk, who often calls him "Bones".
Star Trek: 10 Things You Didn't Know About Dr. Leonard 'Bones' McCoy
How many times did Dr. McCoy say he's dead Jim?
At least twenty times in the original series, Dr. McCoy stated in his matter-of-fact tone, “He's dead, Jim!” whenever an auxiliary character died [“Jim” being Captain Kirk, played by William Shatner). “He's dead, Jim” became a famous catchphrase that entered the lexicon thanks to the cult popularity of the series.
The beloved Vulcan's full name is officially S'Chn T'Gai Spock. The name actually comes from a popular fan work-turned novel for The Original Series in Barbara Hambly's Ishmael which was published in 1985.
In the 19th century, Civil War surgeons were often referred to as "Sawbones" because of the many battlefield amputations they would carry out. Captain Kirk truncates this phrase to "Bones" for his chief medical officer - an ironic sleight given the technology and expertise available on the Enterprise.
While technically only lieutenant commander in rank, McCoy was still the only person on the Enterprise besides Spock who could talk back to the captain and get away with it.
Polycythemia is a real disease in which the body produces too many red blood cells and is not, by itself fatal. Xenopolycythemia would be an alien (xeno- = foreign, alien) variation of the disease.
Winnter's doctors say the theory that a genetic predisposition for adrenal tumors–caused by a genetic disorder called von Hippel-Lindau disease, which Winnter's family carries–is a possible explanation for why the feuding McCoy family members were so violent and angry.
I have done a little investigative work on the Hatfields and McCoys and haven't found a link to an actually Church of Christ congregation. I found in one reference that both families tended to be primitive or hard shell Baptists.
The feud between the Hatfields and McCoys is perhaps the most famous family conflict in American history. At the center of the of the conflict were the two family patriarchs: William Anderson "Devil Anse" Hatfield and Randolph McCoy.
Leonard Nimoy and DeForest Kelley declined to appear as their characters Spock and Leonard McCoy. Nimoy felt there were story problems with the script and that Spock's role was extraneous.
"He's dead, Jim" is a famous catch phrase and snowclone used in Star Trek. It is mostly used by Dr. Leonard McCoy in Star Trek: The Original Series, typically after using his medical tricorder to confirm and report the death to Captain Kirk.
Rounding out the iconic TOS trio, Doctor "Bones" McCoy, played by DeForest Kelley, had a slightly more straightforward timeline in the series. According to canon, McCoy was born in 2227, making him 38 at the start of TOS and 42 by the end of it. This also made him the second oldest character in the main cast.
At the beginning of the third movie, we learn that Spock and Uhura decided to break up, after Spock mentioned his dilemma about going back to New Vulcan, getting married and helping to rebuild instead of going through his Starfleet carrier.
Series creator Bryan Fuller deliberately gave Martin-Green's character a traditionally male name, which he had done with the female leads (George, Jaye and Chuck) in three of his previous series. Martin-Green decided that the character was named after her father.
Uhura's first name was not used in Star Trek canon until Abrams's 2009 film. The mystery regarding Uhura's first name is the subject of a running joke in the film, as Captain Kirk repeatedly tries to find out what it is, before finally hearing Spock call her "Nyota" in a moment of intimacy.
If I remember correctly, McCoy was not in the first episode of TOS, so that implies that he never served under Pike. Likewise, Checkov didn't show up until TOS season 2. I know there are fan theories that he was around for season 1 (and thus met Khan), but wasn't posted to the bridge, so we never saw him.
Nimoy died in February 2015 after a long case of chronic obstructive pulmonary disease (COPD). His death was international news and was met with expressions of shock and grief by fans, Star Trek co-stars, scientists, celebrities, and the media. An asteroid was named 4864 Nimoy in his honor.
