Elven/Mortal marriages...

[The Saucepan Man]

... this choice, since he had chosed immortality, was passed to all of his ancestors since he had chosen deathlessness

Hmm, that would certainly please the likes of Huor, Rian, Galdor, Hareth and Hador, not to mention countless others ... I think that you mean descendants, rather than ancestors. [img]smilies/wink.gif[/img]

But the choice was not passed to all of Elrond's descendants. The choice was passed only to those who had no mortal blood in their veins. So, Arwen, Elladan and Elrohir were all able to make the choice, since both of their parents were immortal. Had Elladan and Elrohir married Elves, their children would, presumably, have had the choice. But Arwen's children were not given the choice because mortal blood flowed in their veins, inherited in fact from both their father and their mother, as Arwen chose mortality.

One question does occur to me, though. Say that all of Elladan's descendants had married Elves, would the mortal element of their make-up at some stage become so diluted that they would become "automatically" immortal without having to make any choice?
