Udea And Her Seven Brothers

Andrew Lang was a Scottish prolific author, mostly known as a collector of folk and fairy tales.
"Udea And Her Seven Brothers" is a short story, entered in "The Grey Fairy Book" collection. A man and wife had seven sons. One day, the sons set out hunting and told their aunt that if their mother had a daughter, to wave a white handkerchief, and they would return at once; but if a son, a sickle, and they would keep on. It was a daughter, but the aunt wished to be rid of the boys, so she waved a sickle. The daughter, Udea, grew up not knowing about her brothers. One day, an older child taunted her for driving her brothers away, who were forever roaming the world; she questioned her mother and set out to find them.
