I believe there was a novel about Spock’s son–not with the Romulan commander, but with Zarabeth, Mariette Hartley’s character from “All Our Yesterdays.”

A physician who very early on studied urine offered to diagnose the King, who brought a sample of a woman’s pee. The Doctor said, “God is about to perform a miracle. The King is pregnant.”
Susan Oliver again, Vina? Vidna? and the green Orion slave girl (who became more and more green as the guys developing the film thought it was a lighting error) in the pilot and The Cage, in the Wagon Train episode, The Emily Rossitter Story. John Dehner, another actor who was all over the place in the 50s and 60s was also in this episode. I don’t believe he was ever in Trek, but he would have been an excellent Harry Mudd.
Her name was Vina. The technician thought the green problem was a flaw in the film, so he used color correction to make the actress look normal.
It wasn’t Susan Oliver in the test film, though. According to Bob Justman (or maybe Herb Solow; I don’t remember), it was actually Majel Barrett. They wanted to see just how green they could paint her and keep it, uhm, “realistic.”
(By way of contrast, Spock ended up yellow instead of red because the latter always looked phoney.)
About the only thing I remember John Dehner in was The Doris Day Show back in the late '60s. He played her boss at the publishing house after the second season or so. (Whether this was before or after McLean Stevenson played her boss, I don’t recall.)
“The Cage” was the original title of the pilot and was changed to “The Menagerie” before it was screened by NBC. It kept that name when it became the first season two-parter, and reverted to it when it was released on video in its original form in the '80s.
I should have said “reverted to ‘The Cage.’” It remains “The Cage” to distinguish it from the two-parter “The Menagerie.”
I’ve probably mentioned this before, but James Cromwell (“Zefram Cochrane” in First Contact) played asshole “Judge Raymond Price” in the Matlock episode “Nowhere to Run.”
Thanks.
I’ll have to give up my Trekker membership card. 
Cromwell actually had four very different ST roles: James Cromwell | Memory Alpha | Fandom
This man gets to keep his trekker card.
There was even a sequel to that one called “Time for Yesterday”. Sometimes I get annoyed that information is even in my brain.
Your Trekker card shall be made of gold plated latnium.

Can I help it that I have a 21st century spell checker?
I, for one, forgive you.
Live long, and prisper.
Arnold Moss played Kodos the Executioner in TOS. He played the same kind of guy, Malek in the Time Tunnel episode, The Walls of Jericho.
Another ST actor turning up on Friends - Larry Hankin, who played Monica’s grumpy, often-complaining downstairs neighbor in several episodes:
John Hoyt, who played Dr. Philip Boyce in Star Trek’s original pilot episode, “The Cage”, played Dr. Varno in the film Time Travelers a couple years earlier. I know this only because I just finished watching the MST3K version of it. And I knew I recognized him from somewhere.
To me, the thing I remember him most for, aside from Doc. Boyce, was “When Worlds Collide” as the wheelchair-bound financier Stanton, who shot his henchman played by Frank (Sam Drucker) Cady.
Soooooooo, beings that we are big consumers of British detective TV shows, we are always on the lookout for similar fare among the Netflix/Amazon Prime entertainment sphere. One that we recently began pursuing is My Life is Murder, an Aussie/NZ based production starring Lucy Lawless of Xena fame. The show is very light, and cliched, but an enjoyable diversion. On the most recent episode released, the plot revolved around a family owned inn. One thread of the plot involved a rich US character who was interested in buying the inn. Initially, the character was only spoken of, as they were reportedly back in the US. So, our hero decides to ZOOM call this rich US dude in order to investigate something something to do with the case. Up pops the ZOOM window and who do we see?
William Shatner! Old Kirk himself, doing a remote acting gig on a frankly minor show. He only had one scene and executed the work admirably. Needless to say, he did not appear 90 years old at all. (Combine good genes with hair, makeup, (a little work over the years, I’m sure) and ZOOM resolution.) Honestly, any US actor of sufficient age and type could have done it. But, apparently Shatner and Lawless have some history together - according to the interwebs at one time he was working on a documentary about Xena? (Unclear if it ever got done?)
