Theseus isn't supposed to have any sisters or brothers.
Theseus had children by both of his wives. His first wife was Hippolyta, Queen of the Amazons. Some also claim that he married Antiope, Hippolyta's sister instead. One child, Hippolytus, resulted from this marriage. Theseus also had a second wife, Phaedra, that bore him two sons, Demorphon and Acamas.
Theseus had several siblings, most notably his half-brothers, including Hippolytus, the son of Theseus and Hippolyta, the queen of the Amazons. He also had a connection to Phaedra, his wife and half-sister, who was the daughter of Minos and Pasiphaë. Additionally, some accounts mention that he had siblings from other unions, but the most prominent are Hippolytus and Phaedra.
He had a daughter named haploids and a son named Adrift.
