oldest person in middle earth

[Boromir88]

lathspell, nice post I'd like to point out the differences between Treebeard being referred to as the Eldest, and Tom B. being referred to as such.

Eldest was the courtesy title of Treebeard as the oldest surviving Ent. The Ents claimed to be the oldest 'speaking people' after the Elves {illegible} until taught the art of speech by the Elves...They were therefore placed after the dwarves in the Old List...since Dwarves had the power of speech from their awaking.~Lord of the Rings Companion, Letter dated 1968

While I think Bombadil being called the 'Eldest' means slightly different (as in he truly is the oldest person on Middle-earth), as he is also referred to as 'fatherless.'
