Aragorn and Arwen Are NOT RELATED

Well, Aragorn had a direct line to Elendil also. I'd say even more direct then Eowen since his was father-to-son in the elder line (thru Isuldur).
Also, in Aragorn's case, there is no "probably" or "ALMOST" certainly, his descent is documented.

Still, it's an interesting observation that even a "wild shieldmaiden of the North" (Eowen) was likely kin to Arwen and had a (very diluted) strain of Maia blood in her (from Melian).
