Eurysthenes in Wikipedia

In Greek mythology, Eurysthenes (Greek: Εὐρυσθένης) was one of the Heracleidae, a great-great-great-grandson of Heracles, and a son of Aristodemus. His twin was Procles, and together they received the land of Lacedaemon after Cresphontes, Temenus and Oxylus captured the Peloponnesus. He was the mythic founder of the Agiad dynasty of the Kings of Sparta, and father of his successor, Agis I. Eurysthenes is also the name of one of the sons of Aegyptus. He was killed by his wife, *Monuste (name uncertain), one of the Danaids.[1]
