Finduilas (wife of Denethor)
In Third Age 2978 she gave birth to a son Boromir, who became loved by his father. In Third Age 2983 she gave birth to her second son, Faramir, and afterwards grew weak. Faramir was ignored by his father, and she did her best to raise him on her own.
In Third Age 2984 Ecthelion suddenly died, and Denethor became Steward of Gondor. Nevertheless the health of the Lady Finduilas dwindled in the city. The shadow of Mordor filled her with horror as she missed the sea, and four years later she died at the very young age of thirty-eight (considering her heritage as a Dúnadan).
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.
