Oh, that gets real fun if you backtrack into Proto-Indo-European cognates using the same root, *h₂ews- "sunrise" - all of the following are cognates:

• Greek ⟨αὔρα⟩ aúrā "breeze", ⟨ἀήρ⟩ āḗr "air". Apparently Proto-Hellenic used those words to refer to the morning mist.
• Latin ⟨aurora⟩ "dawn". Still close to the original meaning.
• Latin ⟨auster⟩ "south". Because in the Northern Hemisphere you'll typically see the sun to the south.
• German ⟨Ost⟩ "east", English ⟨east⟩. It's similar to the above, but closer to the original meaning.
• Latin ⟨aurum⟩ "gold". Etymologically it's roughly "the shining [metal]".
• English ⟨Easter⟩. The name comes from the goddess of dawn Ēastre, associated with April because of spring in the N. hemisphere.
• Albanian ⟨err⟩ "darkness". This one did a 180°: dawn → twilight → darkness.
• Estonian ⟨vask⟩ "copper", Hungarian ⟨vas⟩ "iron". Proto-Uralic borrowed the word from some Indo-European language, but likely used to refer to metals in general.

And it is not even the worst etymological mess I've seen. Like Portuguese getting, like, a half dozen words from Latin ⟨macula⟩.
