Edain/Eldar marriages

[Tar Elenion]

Tuor was a man, Idril was an elf.
Beren was a man, Luthien was an elf.
Aragorn was a man, Arwen was a half-elf.

Those are listed because one half of the relationship was a man. Dior was a half elf, and though he had mortal blood, was not wholly mortal.

Elros was a Half-elf, his wife was a Man.
Notice the similarity between Arwen and Aragorn.
