Who is Elrond's wife?

I'm curious to know, who is Elrond's wife? Is she a figure from Tolkien's legendarium, renowned in her own right? Or is she a lesser-known character, whose story weaves in and out of the larger narrative? Could you elaborate on her characteristics, perhaps mentioning her role in Elrond's life and the impact she might have had on the events surrounding the War of the Rings? I'm fascinated by the intricate web of relationships within Tolkien's Middle-earth, and Elrond's wife seems to be an integral part of that tapestry.
