Dagny
Dagny is a very feminine name and the heroine of the novel Atlas Shrugged. I imagine Dagny as someone who is a strong woman, independent and very feminine- all the traits I would want in a daughter.
Dagny is a name derived from the Old Norse elements dagr meaning "day" and nư, "new". A famous Dagny is Dagny Taggart, the protagonist of Ayn Rand's 1957 novel Atlas Shrugged.
