Cecrops married Metiadusa, daughter of Eupalamus (his brother or a son of Metion), by whom he became the father of his heir, Pandion II.
Mythology
After Poseidon having destroyed Erechtheus and his house during the war between Athens and Eleusis, Cecrops being the eldest of the dead king's children, succeeded to the throne. He was chosen by the appointed judge Xuthus, his brother-in-law, who was accordingly banished from the land by the rest of the sons of Erechtheus.
