In the middle of the 18th century, Matthew Evans kept an inn in the town. He had two sons and a daughter who were celebrated robbers and collectively known as "Plant Mat" ('Matthew's children' in English). They lived for several years in a cave near Devils Bridge which still bears their name. They terrorized the district and would give to their friends a glove to act as a passport and identify them to their brethren. It was difficult to apprehend the trio because of the narrowness of the entrance to the cave which made it impossible to storm. After several years of success, they committed a murder and, eventually being taken, were sentenced to death and executed.
