Long before Tauradain met and married Issiril, he had a lover, Aethelfra, from Rohan who lived with him almost two years in Archet. They had one daughter Aeonwy and then Aethelfra left him and returned to Rohan. What Tauradain did not know is that Aethelfra was pregnant when she left. In Rohan she returned to Marton in the Westfold and raised her daughter and son there. Aeonwy found Tauradain years later, but then he lost track of her. When Taurdred came age, his mother dying told him about his father. After burying his mother, he decided to go north to find Tauradain, not knowing that Tauradain was in Rohan in the wars at that time.
Taurdred came to Bree and was discovered by Issiril. In time she came to love him as her own son, for he was very helpful in the wars around Bree land that the rangers were fighting. Through Issiril, he met their elvish friends, Filegwyn and Meltaurien, who were in Bree to be away from the places they'd lived with Camang. Filegwyn was in deep grief and Meltaurien was comforting her. But Meltaurien's marriage to an elf of Lorthlorien was falling apart, as he did not understand his wife's long absence. Still, the moment Taurdred saw the young she elf, Meltaurien, he was hopelessly in love.
He sent her tokens of love and messages, which she turned away. But upon returning to Lothlorien, she found her husband had divorced her for abandonment and that she was alone there. For some long time, she would receive tokens and love letters from Taurdred, and she threw them all away. But after a while, she would keep them and re-read them. Time passed and she found herself drawn to his sweetness and gentleness, which she had not experienced with her husband. Still, he was a mortal man and she was elf kind and she feared the match her brother, Melgalad had made with the daughter of Taurdain. What would come of her if she dared love a mortal and the son of Tauradain? Still his letters came and still she saved them and re-read them.
Once, after several battles in which she almost lost her life, she felt her existence would not survive this War of the Ring and that the eternal life of the elves was a thing of little value to her if she did not have love. She sent to Taurdred to meet her in Ost Guruth and they became lovers.
Though she forbade him, Taurdred found her in Lothlorien and they were lovers, walking the glades around Echad Andestal for a time. But Galadriel found out and confronted Meltaurien with her love for a mortal. She also spoke to Taurdred, and though Meltaurien was resigned to loving and giving up the immortal life of the eldar, Taurdred felt guilty for asking his love to die for him. So he vanished into Rohan, stopping briefly in Stangard to wish his parents farewell. Tauradain rode to find him, but Taurdred made sure he could not be found, as he feared his parents would tell Meltaurien where to find him. He wanders the damaged towns of the Westfold, disguised as a beggar with a long, shaggy beard, and going by the name of Cearu, which in Rohirrim translates "grief."
Meltaurien at first was hurt that he'd leave her and went with her mother to the west, stopping in Michel Delving, on their way to the ships to Aman. But one day, in a mood, she started riding east and never stopped. Now she fights her way south into Rohan, determined to find Taurdred and confront him.
Finally, when she had reached Stangard, Taurdred heard of it and sent her some supplies. This resulted in a terse exchange between Meltaurien demanding to know where he was and his guilt of taking her immortality because she was elf-kind. Then she learned from her mother that as she and Taurded were already lovers, she had already lost the immortal life of the elves. She wrote this to Taurdred, who blamed himself, and then rushed to her side. The eloped and are now married, living in Stangard and fighting the battles of their respective peoples.
