Was Círdan...

[cesar.ewok]

... married?

I unconsciously said elsewhere that he was assuredly single, but someone brought the question up once more. I had said so probably because I've never seen any mention to some possible wife of Círdan in all Tolkien writings available to me.

Was he married?

[The Might]

Just read through HoMe XII - Last Writings - Círdan and there is no mention of something like that there either.

However, perhaps an explanation for the lack of a partner:

Then, it is said, he stood forlorn looking out to sea, and it was
night, but far away he could see a glimmer of light upon Eressea
ere it vanished into the West. Then he cried aloud: 'I will follow
that light, alone if none will come with me, for the ship that I
have been building is now almost ready.' But even as he said this
he received in his heart a message, which he knew to come from
the Valar, though in his mind it was remembered as a voice
speaking in his own tongue. And the voice warned him not to
attempt this peril; for his strength and skill would not be able
to build any ship able to dare the winds and waves of the Great
Sea for many long years yet. 'Abide now that time, for when
it comes then will your work be of utmost worth, and it will
be remembered in song for many ages after.' 'I obey,' Cirdan
answered, and then it seemed to him that he saw (in a vision
maybe) a shape like a white boat, shining above him, that sailed
west through the air, and as it dwindled in the distance it looked
like a star of so great a brilliance that it cast a shadow of Cirdan
upon the strand where he stood.
As we now perceive, this was a foretelling of the ship (37) which
after apprenticeship to Cirdan, and ever with his advice and
help, Earendil built, and in which at last he reached the shores
of Valinor. From that night onwards Cirdan received a foresight
touching all matters of importance, beyond the measure of all
other Elves upon Middle-earth.

And if he had had any partner, she was probably on the other side of the Great Sea:

Thus he forfeited the fulfilment of his greatest desire: to see the Blessed Realm and find again there Olwe and his own nearest kin.

So it was perhaps because of this 'mission' he had received from the Valar that he did not wish to seek another in M-e, waiting for the Last Ship to bring him to his long lost love.

Then again, maybe he wasn't interested.

[Ibrîniðilpathânezel]

I agree that Tolkien left a rather strong impression that Cirdan was not married. Aside from the aforementioned passages, there is the fact that Tolkien often mentions the children (especially sons) of prominent Elves, even when he never (or only in an obscure reference somewhere in the HoME writings) mentions the names of their wives. No child of Cirdan's is ever mentioned, unless one counts his protective fostering of Ereinion Gil-galad. If Cirdan had had sons, one would think they would have been as brothers to Gil-galad, but nothing of that sort is ever seen.

Still, it's possible that Cirdan had a family, but none of them ever did anything of note and therefore were not mentioned. Somewhere, either in the HoME books or in the letters, I believe Tolkien said that he thought all the sons of Feanor would have been married; I can't recall if he said that their families did not follow them into exile, or if they simply never came up as "players" in the Silmarillion. Celebrimbor appears to have been mentioned because he did things that were noteworthy. The others...? Not a word. So following that pattern, the possibility exists that Cirdan had a wife and descendants, but they were not sufficiently significant to come into the stories.

Nonetheless, I personally feel that in Cirdan, Tolkien was expressing the lot of the classic mythic mariner, for whom the sea is both his calling and his greatest love. The sea is a harsh mistress, and ill tolerates any competition. Moreover, if Cirdan felt himself to be an instrument of some greater destiny, he may have remained deliberately unattached, so that he could fulfill that destiny without risking heartbreak for himself or his loved ones. Just my rambling feelings, here, of course.
