Denethor loved her, in his fashion, more dearly than any other, unless it were the elder of the sons that she bore him. 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. In 2976 of the Third Age she was wed to the much older Denethor, son of Ecthelion II the Steward of Gondor. Named after Finduilas, an Elf-maiden of the First Age, Finduilas of Dol Amroth (2950–2988) was the daughter of Prince Adrahil II, and had an older sister Ivriniel in addition to her brother Imrahil.
Tolkien, Finduilas was the sister of Prince Imrahil of Dol Amroth.
