[Pervinca Took]

I didn't think Emeldir the man-hearted was that obscure. At least she's named in The Silmarillion, and she must be in the Index as well as the family trees. As well as being the mother of a major character. I'm sure we've had similar "ancestry" clues before, and once you had the first letter I didn't think it would be too hard.

That said, I myself have forgotten much lore that I'm sure I once knew. I also very often stare at clues blind to the one element that will solve them.

I have adjusted the N clue - this is how I initially wrote it, but changed it thinking it was too much of a giveaway.

N: Confused lamentation rising from Ivrin's Pools.
ITHILBOR: Mix broth with liquid, adding two eyes, we hear, for the father of a mocker.
POROS: Muddled wild animal’s trail leads to a flower.
HAYSEND: Saruman’s symbol found around troubled affirmative in the Shire.
RHOSGOBEL: Equine creature and online entry mix together in a humble dwelling.
EMELDIR: Dreadful tree mingles for a half-elf’s ancestor.
D: Confused dwarf? Well, the chap has complex parentage.
IVANNETH: Terrible man finds way to join ancient character. It lasts about two fortnights.
L: Record sprinted in minor confusion for a First Age captor.
