So I wondered… Why?
I have said it before and I am saying it again - I am not a big fan of Elrond calling himself a fëanorian, nor am I a fan of him being considered a Noldo.
He is half-elven. It’s referred to so often it is impossible to miss. He is called kin of both Elves and Men, and he associates with both.
But if we have to speak of Elrond strictly as of an elf, I do not think Noldor are the way to go.
In The Peoples of Middle-earth, chapter Problem of Ros, we can find this passage:
The names Elros and Elrond that Elwing gave to her sons were held prophetic, as many mother-names among the Eldar. For after the Last Battle and the overthrow of Morgoth, when the Valar gave Elros and Elrond a choice to belong either to the kin of the Eldar or to the king of Men, it was Elros who voyaged over sea to Númenor following the star of Eärendil; whereas Elrond remained among the Elves and carried on the lineage of King Elwë.
Note 19
And also that of Turgon; though he preferred that of Elwë, who was not under the ban that was laid on the Exiles.
It is said Elrond himself preferred his status as the heir of Elwë over Turgon - and while yes, this book isn’t exactly full-canon and was posted after Tolkien’s death, there are just enough quotes in LotR itself to prove which side of his heritage Elrond preferred.
’… Eärendil was my sire, who was born in Gondolin before its fall; and my mother was Elwing, daughter of Dior, son of Lúthien of Doriath…’
- FotR
Elrond names Eärendil as his father, yes, but that’s it - while with Elwing, he names half of his family tree.
More than that, there are the connections of Elrond and his family to the colour gey - the colour of Sindar, Grey-elves, and their king Elu Thingol.
Almost every time a member of the House of Elrond appears, they are wearing grey or are described in relation to the evening, stars, night.
And while stars are associated with all elves, the combination of all those elements is most common with - you guessed it - Sindar.
[of Elrond] His hair was dark as the shadows of twilight, and upon it was set a circlet of silver; his eyes were grey as a clear evening, and in them was a light like the light of stars.
-FotR
[of Arwen] … and the light of stars was in her bright eyes, grey as a cloudless night; yet queenly she looked, and thought and knowledge were in her glance, as of one who has known many things that the years bring. Above her brow her head was covered with a cap of silver lace netted with small gems, glittering white; but her soft grey raiment had no ornament save a girdle of leaves wrought in silver.
- FotR
[of Elladan and Elrohir] …two tall men, neither young nor old. So much alike were they, the sons of Elrond, that few could tell them apart; dark-haired, grey-eyed, and their faces elven-fair, clad alike in bright mail beneath cloaks of silver-grey.
- RotK
Elrond wore a mantle of grey and had a star upon his forehead, and a silver was in his hand, and upon his finger was a ring of gold with a great blue stone, Vilya, mightiest of the Three.
- RotK
There are more connections - Elladan and Elrohir bearing a silver banner, the above mentioned Grey Company who are known friends of the House of Elrond, as well as descendants of Númenor, and others.
In Problem of Ros, we also have this bit:
Now Elrond was a word for the firmament, the starry dome as it appeared like a roof to Arda; and it was given by Elwing in memory of the great Hall of the Throne of Elwë in the midst of his stronghold of Menegroth that was called Menelrond, because by the arts and aid of Melian its high arched roof has been adorned with silver and gems set in the order and figures of the stars in the great Dome of Valar in Aman, whence Melian came.
More connection to stars, to Menegroth, to Elwing, to Thingol.
And of course, of Thingol himself:
… Elu Thingol he was called, King Greymantle, in the tongue of his people. They are called the Sindar, Grey-elves, of starlit Beleriand; and although they were Moriquendi, under the lordship of Thingol and the teaching of Melian they became the fairest and the most wise and skillful of all the Elves of Middle-earth.
- The Silmarillion
Greymantle. Grey-elves. Starlit Beleriand. Constant references of Thingol and Sindar being connected to the colour grey, stars. Another interesting thing people seem to forget is that Sindar were wise and skilled and not lesser than Noldor, just different - and even than not much as Noldor and Teleri were told to be alike. Daeron constructed Cirth and was a bard of great renown; Lúthien was… Lúthien, which I don’t think needs an elaboration; Mablung and Beleg were respected outside of Doriath; Celeborn, called the Wise; Thranduil, a Sinda who would not fight a war over gold (which is always a smart decision); Elwing who was brave and did the best she could (and before anyone goes at me about Elwing, I recommend this post and reading the notes on it).
Outside of them, it is the House of Elrond and Dúnedain who gets connected to the colour grey the most. I don’t think it is a stretch to say that of his elven ancestry, he prefers the heritage from his mother.
In the end I see him as a Sinda-Númenorean who has just enough eldtrichness to show he is a descendant of Melian - and maybe a bit more of it when needed. However, he respects all sides of his heritage - and despite me saying he doesn’t see himself as a Noldo, he doesn’t have any problem with Noldor, nor does he ignore or dislikes that side of his heritage. He is proud of it and bears many Noldorin traits. He taught his children to be the same. It just isn’t the most prominent part of him.
I think his tendency to stand in the background rather than lead himself is also a trait more of Sindar than Noldor, for… Obvious reasons. Most of the Noldor in the First Age fought a battle after a battle, rushed into reckless valiant acts. But if we see Sindar in battle, it’s most often because they were attacked first; as a last resort; unexpected kicking ass in Lúthien style; because they see no better option.
And in the end, grey is not exactly a distinctive colour - it tends to fade into the background, but is no less than important.
Just like Elrond. Just like Sindar.
