I identified Chagrith as the Reman officer played by Robertson Dean based on the striped pattern on his shoulders. None of the other Reman images on Memory Alpha have the same shoulder pads. However, Memory Alpha mentions a Reman subcommander played by Michael Wickson who doesn't currently have an image, so maybe that's the real Chagrith. Or Chagrith and "Thalpet" could be the same character given two different names. Even the real CCG sometimes did that.
Hawk was given the Borg designation 1701dashEspace587M in the short story "A Private Victory" from Strange New Worlds III.
Seems a pity it wasn't continued officially (though it depends on what "official" and "unofficial"). The names they've come up really adds to the lore of both Alpha and Beta canon.
Haven't found copies of SNW short stories anywhere in Australia (yet). I did read The Sky's the Limit short stories briefly and it got me the idea of there being two
Melbournes at Wolf 359 (neither being Hanson's flagship as the script gives him a
Galaxy, not sure where the idea either
Melbourne was the flag when the
Excelsior-class was destroyed at the start of the battle and the
Nebula-class variant (
Melbourne-class?) was at least in the first couple of waves and I doubt a flagship would lead the charge --- unless you're Benjamin Sisko and have a ship with ablative armour and a hurry to get to DS9 before the wormhole is opened). I still can't find the
First Contact novelisation because it is used as the official source for "U.S.S.
Reliant" being at Sector 001 and Eiger's first name being "Inge". I found the junior novelisation and they used "Alice", which i think sounds nicer.
I also treat "Royse" and "One of Eleven" as separate characters, since they were portrayed by two different actors. There were at least two assimilated Bolian Borg Drones in Engineering so either one of them could've been the assimilated "Royse". Hint for "Lisa Azar" and "Richard Wilkins" and where they are, check Engineering as Geordi is putting Alpha team together, Wilkins is with Eiger at the main station while Azar is walking behind them and then out of Engineering as Geordi comments on the temperature being raised. It's also where "Suzanne Dumont" (Steph Silvestri) is, the one handing him his case before they leave. The CCG has the error for "Obarakeh" and "Joseph Travis", their ranks are given as Ensign on the cards but glances at their collars indicate they're either "lieutenant jg" or "lieutenant".
One thing I've done (which I've done for another fandom I shall not name) is what's called "Naming the Unnamed". I just find names for unnamed characters, ships, species and perhaps locations. It's not official or even unofficial. Just what I feel works. For example: the different names for David Ralphe's character and J. Patrick McCormack's character in NEM, the former being either Bezor (novelisation), Talvin (CCG) and D'Ral (CCG) -- he becomes Talvin D'Ral Bezor -- while the latter has either Talik (novelisation) and Noram (CCG) -- he becomes Noram (made-up middle) Talik. Valtane's novelisation name Masoud becomes his middle name: Dimitri Masoud Valtane. Dr. Nichols, with his various first names, becomes just Marcus Walter "Mark" Nichols (I liked Marcus). And the Andorian commodore in TVH, I made him Thelin from TAS (and expanded his name, same with Igrilan Kor and S'rrel). It's a fun thing I decided to do for myself.
