> (Wodan is the Germanic/celtic version of Odin.)

[Wikipedia:] The Old Norse theonym Óðinn (runic ᚢᚦᛁᚾ on the Ribe skull fragment) and its various Germanic cognates – including Old English Wōden, Old Saxon Wōdan, Old Dutch Wuodan, and Old High German Wuotan (Old Bavarian Wûtan), – all derive from the reconstructed Proto-Germanic masculine theonym Wōđanaz (or Wōdunaz).

My personal favorites, missing from this list, along with improbable etymology, are Wudan, Wudang, Wutan and Wutang.
