Who are the Moyers in Fallout 4?
At first I wasn't sure if October 6 said Dinner with the "Mayors" or Dinner with the "Moyars", but after exiting the vault and being able to crouch, looking closer I could tell that the writer of the memo has a pronounced difference between their "a" and their "o" (see October 4's memo, the second word, "handy"), concluding that the entry is certainly "Moyers".
However, I can't find a single reference to them at all on the internet, nor have I found any relevant terminal entries so far (though there are a lot to go through). Do they even exist beyond this scribble?
Note: I started looking into this because the Sole Survivor's neighbors, with whom the SS may or may not had friendships, are named, have wiki pages, and some even make appearances later in the game. In contrast, the Moyers, despite having a rather apparent connection to the SS, essentially seem to not exist. Who are they?
By increasing the contrast, we can see that the name is actually "Mayers" or "Moyers":
Considering that Fallout 4 is set 210 years later, that Vault 111 was the only Vault we know of that experimented on cryogenic sleep, and that you're the only survivor of Vault 111 (aside from Shaun, your child), it's highly likely that the Mayers/Moyers probably either died long before Fallout 4 started (ignoring the introduction 210 years ago) or have since become Ghouls.
With that in mind, I've been searching for both names, and nothing came up. The only match I got was a https://fallout.fandom.com/wiki/Meyers , but this is clearly neither the same person nor the same name.
Thus I believe the evidence (or lack thereof) indicates that the Mayers/Moyers probably never existed aside from that one note.
