Title: Odysseus
Content:  Relatively little is given of Odysseus' background other than that according to Pseudo-Apollodorus, his paternal grandfather or step-grandfather is Arcesius, son of Cephalus and grandson of Aeolus, while his maternal grandfather is the thief Autolycus, son of Hermes and Chione. Hence, Odysseus was the great-grandson of the Olympian god Hermes. According to the Iliad and Odyssey, his father is Laertes and his mother Anticlea, although there was a non-Homeric tradition that Sisyphus was his true father. The rumour went that Laërtes bought Odysseus from the conniving king. Odysseus is said to have a younger sister, Ctimene, who went to Same to be married and is mentioned by the swineherd Eumaeus, whom she grew up alongside, in book 15 of the Odyssey.
Title: Odysseus
Content:  Odysseus, also known by the Latin variant Ulysses , is a legendary Greek king of Ithaca and the hero of Homer's epic poem the Odyssey. Odysseus also plays a key role in Homer's Iliad and other works in that same epic cycle. Son of Laërtes and Anticlea, husband of Penelope, and father of Telemachus and Acusilaus, Odysseus is renowned for his intellectual brilliance, guile, and versatility (polytropos), and is thus known by the epithet Odysseus the Cunning. He is most famous for his nostos, or "homecoming", which took him ten eventful years after the decade-long Trojan War.
Title: Telemachus
Content:  Telemachus (Ancient Greek: Τηλέμαχος Tēlemakhos, literally "far-fighter"), in Greek mythology, is the son of Odysseus and Penelope, who is a central character in Homer's Odyssey. When Telemachus reached manhood, he visited Pylos and Sparta in search of his wandering father. On his return to Ithaca, he found that Odysseus had reached home before him. The first four books of the Odyssey focus on Telemachus's journeys in search of news about his father, who has yet to return home from the Trojan War, and are traditionally given the title the Telemachy.
Title: Telemachus
Content:  did not recognise his father until the latter disclosed to him who he was. Father and son now agreed to punish the suitors; and when they were slain or dispersed, Telemachus accompanied his father to the aged Laertes. (Hom. Od. xv.–xxiv.; comp. Odysseus.) In the post-Homeric traditions, we read that Palamedes, when endeavouring to persuade Odysseus to join the Greeks against Troy, and the latter feigned idiocy, placed the infant Telemachus before the plough with which Odysseus was ploughing (Hygin. Fab. 95; Serv. ad Aen. ii. 81; Tzetz. ad Lycoph. 384; Aelian, V. H. xiii. 12.). According to some accounts, Telemachus became the father of Perseptolis either by Polycaste, the daughter of Nestor, or by Nausicaa, the daughter of Alcinous (Eustath. 
Title: Polybus (Odyssey)
Content:  In Ancient Greek epic tradition recounted in Homer's Odyssey, Polybus was the father of a suitor, Eurymachus, who was killed by Odysseus once he returned from his 10-year journey during the Trojan War.
Title: Odyssean gods
Content:  Poseidon is the Greek god of the sea and the brother of Zeus, Hades, Hera, Hestia and Demeter. Beckoned by the curse of Polyphemus, his one-eyed giant son, he attempts to make Odysseus' journey home much harder than it actually needs to be. He appears to be very spiteful in the Odyssey and actively causes problems for Odysseus on sight. Although he cannot kill Odysseus, as it is his destiny to return home, he makes every effort to make Odysseus suffer. Odysseus earned Poseidon’s wrath by blinding Polyphemus. While the blinding alone may have been justifiable for the poor mistreatment by Polyphemus to his guests, Odysseus's pride was really what incurred Poseidon’s wrath. As Odysseus was leaving the island of the Cyclops behind, he mocked and talked down on Polyphemus and accused him of being impious. Polyphemus exclaimed that he was the son of Poseidon, yet 
Title: Telegonus (son of Odysseus)
Content:  When Telegonus had grown to manhood, his mother Circe sent him in search of Odysseus, who by this time had finally returned to Ithaca from the Trojan War. Shipwrecked on Ithaca by a storm, Telegonus believed mistakenly that he had made landfall on Corcyra (Corfu) and, assailed by hunger, began plundering the island. Odysseus and his oldest son, Telemachus, defended their city and, in the ensuing melée, Telegonus accidentally killed his father with a lance tipped with the venomous spine of a stingray. Telemachus married Telegonus's mother, the enchantress Circe, while Telegonus took to wife Odysseus's widow Penelope. By Penelope, he was the father of Italus 
Title: Circe
Content:   Towards the end of Hesiod's Theogony (c. 700 BC), it is stated that Circe bore Odysseus three sons: Agrius (otherwise unknown); Latinus; and Telegonus, who ruled over the Tyrsenoi, that is the Etruscans. The Telegony, an epic now lost, relates the later history of the last of these. Circe eventually informed her son who his absent father was and, when he set out to find Odysseus, gave him a poisoned spear. When Telegonus arrived to Ithaca, Odysseus was away in Thesprotia, fighting the Brygi. Telegonus began to ravage the island; Odysseus came to defend his land. With the weapon Circe gave him, Telegonus killed his father unknowingly. Telegonus then brought back his father's corpse to Aeaea, together with Penelope and Odysseus' son by her, Telemachus. After burying Odysseus, Circe made the other three immortal. Circe married Telemachus, and 
Title: Nausithous

He was the son of the god Poseidon and Periboia, the daughter of the Giant king Eurymedon. According to Homer, Nausithous led a migration of Phaeacians from Hypereia to the island of Scheria in order to escape the lawless Cyclopes. He is the father of Alcinous and Rhexenor. Alcinous would go on to marry his niece, Rhexenor's daughter Arete. One source relates that Heracles came to Nausithous to get cleansed after the murder of his children; during his stay in the land of the Phaeacians, the hero fell in love with the nymph Melite and conceived a son Hyllus with her. ; Nausithous, one of the two sons born to Odysseus by Calypso, the other one being Nausinous.
