|Tilda is a concept which has only appeared in an adaptation of the works of J.R.R. Tolkien.|
Tilda, the daughter of Bard, had an older sister Sigrid, who looks after her when their father is at work, and an older brother, Bain. 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, Tilda and her siblings hid in the Great Hall on the main square, although their journey there was beset with dangers.
