What follows is something extremely sensitive to my imaginations...
Elendil is a direct decendent of the line of Elros, brother of Elrond half-elven.
Aragorn son of Arathorn II is a direct decendent of Elendil. It follows therefore that Elrond half-elven can be considered as Aragorn's great-great....(multiply with some number between 20 to 40) grand Uncle.
So, Arwen Evenstar is Elrond's daughter, and Aragorn's great-great... (multiply with some number between 20 to 40 minus 1) grand Aunt...
Gee, before anyone come after me with some firebrand, I would like to mention that majority, if not all of their ancestors are related anyway from the beginning... note: Luthien and some guy... I have not checked the exact family tree yet... but this assumation I think stands to reason, since Prof T likes to his royalty bloodlines to be PURE.
Ah! Just laugh it off!
