She is a girl of Sleepy Hollow, which like the other women of the village, shows a liking to Ichabod.
During the party organized by Baltus Van Tassel, Brom Bones notices Tilda has no dance partner, and decided to use her as a way to swap her with Katrina. This comically backfires as Tilda, excited about having someone to dance with, will not let go of him.
