|Sigrid is a concept which has only appeared in an adaptation of the works of J.R.R. Tolkien.|
Sigrid was the eldest daughter of Bard and the sister of Bain and Tilda. She tended the family's house in Lake-town and looked after her younger sister Tilda while Bard was away at work. During the onslaught of Smaug, she escaped the town with her sister, the Elf Tauriel and the Dwarves. They relocated to the ruins of Dale.
After the Orcs attacked Dale, Sigrid and her siblings hid in the Great Hall on the main square, although their journey there was beset with dangers.
