I was looking at the Noldor House of Finwë descendancy and on one side it shows Arwen, daughter of Elrond as we all know. But I didn't know this part: the other side breaks off into Aragorn as a descendant of Elros - Elrond's twin brother. Does that make them cousins?

  • To everyone here using family trees off the webz, I'm not sure where these find their source? For all I know, the books would be the only sources that may decide this. But I know that most of the names in these family trees are never mentioned.

Using the family-tree from http://lotrproject.com/, by my quick-count it seems Arwen and Aragorn II are first-cousins either 62 or 67 times removed, depending on whether you go through Aragorn's great x 14 grandfather (Arvedui) or great x 14 grandmother (Firiel) who both descended from Elendil (Arvedui on the Isildur side, Firiel on the Anarion side).

Hence Elendil is Aragorn's great x 38 grandfather as well as Aragorn's great x 43 grandfather.

The short answer is yes, they're directly related (first cousins) albeit separated by a very considerable age gap.

This handy family tree from The Encyclopaedia of Arda should be helpful to you:

Arwen Aragorn

Please note that the dotted line between Elros and Aragorn represents many thousands of years of lineage on Aragorn's side of the family.

    The men of Numenor are long-lived, but this still represents something like 50 generations of descent between Elros and Aragorn. (We could get a rough idea how many by counting the Kings of Numenor and later of Arnor, but I can't be bothered to go get my copy of LOTR and do that just now.) In real-world terms it would be like marrying someone you shared an ancestor with about 1000 years ago. Any two people from (say) the same European country are likely to have a common ancestor if you go this far back. Commented May 22, 2014 at 20:55

    @JimmyShelter - Yes, the chart is a bit of fluff designed to illustrate the foolishness of trying to backtrack familial relations over millenniun. At any point this lineage could easily have been illegitimised by a bored queen and a bottle of cheap bordeaux.

    @PaulDraper, the technical term for generational differences of this sort is "removes", eg. if your grandfather was my great-grandfather, we'd be "first cousins once removed". Aragorn and Arwen are "first cousins fifty-someodd times removed".

    @WhatRoughBeast: "When the cousins are not the same generation, they are described as "removed". In this case, the smaller number of generations to the common ancestor is used to determine the degree, and the difference in generations determines the number of times removed." So the smaller number of generations to the common ansestors is one, so they're first cousins. Did you read the page you linked? Commented May 23, 2014 at 16:09

Very distant first cousins, many many times removed.
