Ascanius
A son of Aeneas by Creusa (Aeneid by Virgil), or by Lavinia. (Livius) From Livy it would seem that some traditions distinguished between an earlier and a later Ascanius, the one a son of Creusa, and the other of Lavinia.
After the fall of Troy, Ascanius and some Phrygian allies of the Trojans were sent by Aeneas to the country of Dascylitis, whose inhabitants made Ascanius their king; but he soon returned to Troy, and ruled there after the death of his father, who, according to some traditions, had likewise returned to Troy. (Dionysiaca)
Another legend made Ascanius found a new kingdom at Scepsis in Troas, in conjunction with Scamandrius, the son of Hector. (Strab. xiii. p. 607.) Others again, according to whom his original name was Euryleon, made him accompany his father to Italy and succeed him as king of the Latins. (Dionys. i. 65.) Livy states that on the death of his father Ascanius was yet too young to undertake the government, and that after he had attained the age of manhood, he left Lavinium in the hands of his mother, and migrated to Alba Longa. Here he was succeeded by his son Silvius.
According to Dionysius (i. 70), Silvius was a younger brother of Ascanius, and disputed the succession with Julus, a son of Ascanius. The dispute was decided in favour of Silvius. Servius (ad Aen. i. 271) states, that Ascanius was also called Ilus, Julus, Dardanus, and Leontodamus.
The gens Julia at Rome traced its pedigree up to Julus and Ascanius. In the stories about Troy there occur three other personages of the name Ascanius. (Apollod. iii. 12. § 5 ; The Aeneid by Virgil)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Historia Brittonum by Nennius
Respecting the period when this island became inhabited subsequently to the flood, I have seen two distinct relations. According to the annals of the Roman history, the Britons deduce their origin both from the Greeks and Romans. On the side of the mother, from Lavinia, the daughter of Latinus, king of Italy, and of the race of Silvanus, the son of Inachus, the son of Dardanus; who was the son of Saturn, king of the Greeks, and who, having possessed himself of a part of Asia, built the city of Troy. Dardanus was the father of Troius, who was the father of Priam and Anchises; Anchises was the father of Aeneas, who was the father of Ascanius and Silvius; and this Silvius was the son of Aeneas and Lavinia, the daughter of the king of Italy. From the sons of Aeneas and Lavinia descended Romulus and Remus, who were the sons of the holy queen Rhea, and the founders of Rome. Brutus was consul when he conquered Spain, and reduced that country to a Roman province. He afterwards subdued the island of Britain, whose inhabitants were the descendants of the Romans, from Silvius Posthumus. He was called Posthumus because he was born after the death of Aeneas his father; and his mother Lavinia concealed herself during her pregnancy; he was called Silvius, because he was born in a wood. Hence the Roman kings were called Silvan, and the Britons from Brutus, and rose from the family of Brutus.
From The Aeneid by Virgil Book IV
Then, when they part, when Phoebe's paler light Withdraws, and falling stars to sleep invite, She last remains, when ev'ry guest is gone, Sits on the bed he press'd, and sighs alone; Absent, her absent hero sees and hears; Or in her bosom young Ascanius bears, And seeks the father's image in the child, If love by likeness might be so beguil'd.
