Legend
I find it striking how much love there is for the Forgotten Realms pantheon and the Dawn War pantheon given the similarity in how they were built, i.e. pull gods from various fictional and real world myths and either rename them or just use them as-is. And then create a couple new ones for the heck of it. Don't believe me?
. . .
Forgotten Realms
Tyr = Norse
Ilmater = Finnish
Mielikki = Finnish
Loviatar = Finnish
Oghma = Finnish
Shar = Hel, renamed
Silvanus = Celtic
Tempus = Ares, renamed
Sune = Aphrodite, renamed
Milil = Apollo, renamed
Chauntea = Demeter/Ceres, renamed
Tymora = Tyche, renamed
And so on. As an aside, I'm pretty sure Ed just plucked the Finnish gods straight from Deities & Demigods.
Pretty close on your list.
In Dragon 54 (I love the Dragon CD archive) Greenwood lays out how he went through the 1e DDG in working through his pantheon and his design goals and what the origins of different gods are.
Azuth is a renamed Aarth from Nehwon.
Bane is equivalent to Celtic Druaga without ruling the devils (in 4e they pushed him as Ares pretty hard).
Chauntea is Demeter.
Gond is Hephaestus
Ilmater is not Finnish but Issek of the Jug from Nehwon.
Loviatar is Finnish.
Mask is Hermes rewritten.
Mielikki is Finnish.
Millil is not Apollo (Later sources push Lathander as essentially Apollo).
Oghma is Celtic.
Shar is not Hel.
Silvanus is Celtic.
Sune is Aphrodite.
Talona is Kiputytto from the Finnish.
Talos is an amalgam of storm god features that appealed to him.
Tempus is not Ares, he is mysterious and Greenwood says the DDG war god power levels were generally too powerful for what he wanted.
Tyche is a combo of Tyche and Bes. (Later 2e sources put out a thing that Moander infected Tyche and she split into Beshaba and Tymora, though 54 has Beshaba and Tyche as separate gods).
Tyr is norse minus the war aspect.
The elemental gods are straight out of Moorcock, not even renamed yet.
He also takes the Moorcock Beast Cults but adds in some things like the Nehwon rat god, Apep from Egypt as the snake, Lolth as a spider cult figure, and four he created, Besparr, Hyyaak, Aslan (based on Narnia and some rhyme about a Lion and a Unicorn) and Lurue the Unicorn (also based on the rhyme but also The Little White Horse).
Also taking existing gods from other pantheons and either adding them in straight or modifying them along with originals has a long tradition. See Apollo being pulled in straight from Greek to Roman and Ares being renamed Mars and having different aspects particularly along the barbaric versus civilized axis (and agriculture) while Janus is a Roman only god.
