Celebrimbor doesn't actually appear in JRR
Tolkien's
Quenta Silmarillion. Christopher Tolkien edited him in there, based on a
note from JRRT [see the contents of
the note below].
A little
external history:
Celebrimbor was a Jewel Smith of
Gondolin until Tolkien changed his mind and re-imagined him as a descendant of
Feanor. Tolkien then
published that Celebrimbor was a descendant of Feanor in the
second edition of
The Lord of the Rings (1966) . . .
. . .
then (it appears) Tolkien forgot that he'd already
published Celebrimbor as a descendant of Feanor, or in any case made him a Telerin
Elf who accompanied
Celeborn into exile [from Aman!].
And in yet another late text, Tolkien made Celebrimbor into
"a Sinda who claimed descent from
Daeron" [
Of Dwarves and Men].
Cough. What was the question? Oh yes.
Again, since Tolkien himself published that Celebrimbor was a descendant of Feanor, I hold him to that idea, and according to his own commentary,
even Christopher Tolkien thinks that his father would have felt bound by this as well (that is, had his father remembered).
So Feanorean it is!
The note: JRRT wrote that
0) though a son of
Curufin and inheriting his skills, Celebrimbor was an Elf
of wholly different temper
1) during his dwelling in
Nargothrond Celebrimbor grew to love
Finrod 2) Celebrimbor was aghast at the behaviour of his father Curufin, and so, he would not go with him, and
3) that later he became a friend of Celeborn and
Galadriel.
The note also relates that
4) Celebrimbor's mother had refused to take part in the Rebellion of Feanor, and had remained in
Aman with
Finarfin's folk,
so it appears at least, that Celebrimbor was born in Aman.
