Celebrían was daughter of Celeborn and Galadriel, the wife of Elrond, the mother of Elladan, Elrohir and Arwen, and the mother-in-law of Aragorn.
History[]
Early Life[]

Celebrian was the daughter of Galadriel and Celeborn of Lothlorien
Celebrian was born between SA 350 and SA 400, living with her parents in Eregion, but later fled to Lorin and to Rivendell, where she met Lord Elrond.
Marriage[]
Celebrian and Elrond had a loving relationship, eventually marrying. The couple had three children: twin sons, Elladan and Elrohir and one daughter, Arwen . In TA2509, while going to visit her parents in Lothlorien, Celebrian and her company were waylaid by orcs. The poor woman was tortured by the Orcs for weeks before she was saved by her two sons. Though Elrond fully healed her, she was never fully healed in her mind and left Middle-earth in TA 2510, journeying to the Gray Havens to be with her kin.

After his marriage with Arwen, Aragorn became the son-in-law of Celebrian

Celebrian later fled to Rivendell where he met and wed Lord Elrond
After Arwen married Aragorn, Celebrian became his mother-in-law and Eldarion's maternal grandmother. Eventually, she was possibly reunited with her husband and parents when they left Middle-earth for the Gray Havens with the Hobbits Bilbo Baggins and Frodo Baggins and the wizard Gandalf.
