Passage 7.2.3
τρίτον δὲ τότε οἱ Κόδρου παῖδες ἐπετάχθησαν Ἴωσιν ἄρχοντες, οὐδέν σφισι γένους τοῦ Ἴωνος μετόν, ἀλλὰ Μεσσήνιοι μὲν τῶν ἐκ Πύλου τὰ πρὸς Κόδρου καὶ Μελάνθου, Ἀθηναῖοι δὲ ὄντες τὰ πρὸς μητρός. Ἴωσι δὲ τοῦ στόλου μετασχόντες ἦσαν οἵδε Ἑλλήνων, Θηβαῖοί τε οἱ ὁμοῦ Φιλώτᾳ γεγονότι ἀπογόνῳ Πηνέλεω καὶ Ὀρχομένιοι Μινύαι συγγενείᾳ τῶν Κόδρου παίδων·
Then thirdly, the sons of Codrus were appointed rulers over the Ionians, although they themselves had no share in the lineage of Ion. Rather, they were Messenians from Pylos on their father's side, descended from Codrus and Melanthus, and Athenians on their mother’s. The following groups of Greeks participated alongside the Ionians in this expedition: the Thebans who joined with Philotas, a descendant of Peneleus; and the Minyan Orchomenians, who were related by blood to the sons of Codrus.
