DISCLAIMER: Companions are referred to by their first names here, even if usually referred to by their surnames or another title in series. Nicknames that are short forms of names are used, nicknames that are not a form of the name are not. A good number of the names here are probably not at all what the creators were thinking - they just made up a name, and it coincidentally resembled a real one. Only one name I could not find any real world equivalent of. If a name is officially a short form of a name I cannot find any evidence of being used, but resembles a more common name, I will use the latter. Companions whose names are English words are on the list, companions whose names are puns on English words are not. Companions are ordered as chronologically as possible, but for non-regular companions that's more difficult, and so they are decided according to my judgement. Basically it's all kind of arbitrary but if you don't like it make your own photoset.
