'Mithrellas'

Mithrellas
Elven ancestor of the Princes of Dol Amroth. Mithrellas was a Silvan Elf of Lothlorien. She was one of many Silvan Elves who fled from Lothlorien in 1081 after the Balrog awoke in nearby Khazad-dum. Mithrellas was a companion of Nimrodel, the lover of King Amroth of Lothlorien. On the journey south, Nimrodel and her companions became lost in the White Mountains.
Mithrellas was given shelter by a Numenorean named Imrazor who lived in Belfalas. She married Imrazor and they had two children - a son named Galador and a daughter named Gilmith. One night, Mithrellas slipped away and was never seen by her husband again. She may have gone to wander in the woods, or she may have sought the haven of Edhellond to depart over the Sea.
Mithrellas' son Galador was the first Lord of Dol Amroth. His descendants thus had Elven blood, as was noted by Legolas when he met Prince Imrahil.
?The name Mithrellas may be composed of mithren meaning "grey" and las meaning "leaf."

An Elven-maid there was of old,
A shining star by day:
Her mantle white was hemmed with gold,
Her shoes of silver-grey.

A star was bound upon her brows,
A light was on her hair
As sun upon the golden boughs
In Lórien the fair.

Her hair was long, her limbs were white,
And fair she was and free;
And in the wind she went as light
As leaf of linden-tree.

Beside the falls of Nimrodel,
By water clear and cool,
Her voice as falling silver fell
Into the shining pool.

Where now she wanders none can tell,
In sunlight or in shade;
For lost of yore was Mithrellas
And in the mountains strayed.

The elven-ship in haven grey.
Beneath the mountain-lee
Awaited her for many a day
Beside the roaring sea.
