In TA 2976 of the Third Age she was wed to the much older Denethor II, son of Ecthelion II the Steward of Gondor. A description of Lady Finduilas is given in Appendix A of The Lord of the Rings The Return of the King: "She was a lady of great beauty and gentle heart, but before twelve years had passed she died. Denethor loved her, in his fashion, more dearly than any other, unless it were the elder of the sons that she bore him. But it seemed to men that she withered in the guarded city, as a flower of the seaward vales set upon a barren rock. The shadow in the east filled her with horror, and she turned her eyes ever south to the sea that she missed." 
In TA 2984 Ecthelion suddenly died, and Denethor became Steward of Gondor. Nevertheless the health of the Lady Finduilas dwindled, and four years later she died at the very young age of thirty-eight (considering her heritage as a Dúnedain). Denethor never remarried, and "became more grim and silent than before."  It was not long after her death that he "would sit long alone in his tower deep in thought, foreseeing that the assault of Mordor would come in his time." Thus he began using the Palantír of Minas Tirith, and the despair fed to his mind led to his ultimate insanity and suicide some thirty-one years later.
