A couple of fan reference publications from the '80s gave Spock a "first name" that was a string of consonants, something like Xflswrntzglb, though that's not it.
The name Xtmprszntwlfd, suggested by DC Fontana, IIRC, came from the same ask-the-experts convention panel as the coining of Tiberius, by David Gerrold, for Kirk's middle name starting with T, which he then made a point of adding to the script of "Bem" (TAS). It was at similar panels that Penda Uhura and Walter Sulu were popularised and passed into early "fanon", with approval of Nicholls and Takei.
Hikaru Sulu came from "The Entropy Effort" and was canonised in ST VI. Nyota Uhura came from "ST II Biographies" and was popularised by "Uhura's Song".
I said to leave it be. I asked you to leave it be. I really didn't think you would, but truthfully, there's a part of me that hoped you would (like an annoying sit-com character that you need tomake the show complete) but I asked you to leave it alone.
He
did leave it be. He avoided discussion of apostrophe names completely, and told a different anecdote.
