Werewolf: the Apocalypse auspice name etymologies

Question

As part of his question about the etymologies of the auspice names in Werewolf: The Forsaken, @OpaCitiZen discusses the origins of "theurge":

What I'm looking for: I remember, for example, that the word "theurge" (used in the oWoD Werewolf, also an auspice) comes from "theurgy", which Google defines as "the operation or effect of a supernatural or divine agency in human affairs" and, still according to Google, has its roots in the Greek "theos" (god) and "-ergos" (working), which combine into "theourgia" (sorcery), which makes it pretty obvious why the designers of that game picked it.

Now, in my answer, I noted that the Forsaken names are the Apocalypse names gone backward through Grimm's Law. But that begs the question of just what the Apocalypse auspice names mean. So, given that, from where do Ragabash, Galliard, Philodox, and Ahroun come?

Answer 1

Here are the answers I have so far:

• "Ragabash" is English; it means "ragamuffin" or "A shiftless, disreputable fellow."
• "Galliard" is from Old French; it means "lively, brisk, high-spirited." It's also a dance.
• "Philodox" goes back to Greek, meaning "opinion-lover." Someone enraptured with his own ideas.
• "Ahroun" is of unknown provenance, but probably onomatopoeia for a Garou's howl to the moon.
