In the Iliad book XX Aeneas briefly fights Achilles. Before they fight there is some trash talking where Achilles reminds Aeneas of the previous times they have fought and Aeneas has had to retreat. Aeneas responds with a summation of his noble lineage, being the son of Aphrodite for one thing. He also sums up the lineage of the Trojans themselves.

I am just going to post a block of text now:

"In the beginning Dardanus was the son of Jove, and founded Dardania, for Ilius was not yet stablished on the plain for men to dwell in, and her people still abode on the spurs of many-fountained Ida. Dardanus had a son, king Erichthonius, who was wealthiest of all men living; he had three thousand mares that fed by the water-meadows, they and their foals with them. Boreas was enamoured of them as they were feeding, and covered them in the semblance of a dark-maned stallion. Twelve filly foals did they conceive and bear him, and these, as they sped over the rich plain, would go bounding on over the ripe ears of corn and not break them; or again when they would disport themselves on the broad back of Ocean they could gallop on the crest of a breaker. Erichthonius begat Tros, king of the Trojans, and Tros had three noble sons, Ilus, Assaracus, and Ganymede who was comeliest of mortal men; wherefore the gods carried him off to be Jove's cupbearer, for his beauty's sake, that he might dwell among the immortals. Ilus begat Laomedon, and Laomedon begat Tithonus, Priam, Lampus, Clytius, and Hiketaon of the stock of Mars. But Assaracus was father to Capys, and Capys to Anchises, who was my father, while Hector is son to Priam."

Ilus, referenced above, was the founder of the city itself. Troy is a more general descriptor of the surrounding area, and was named for Tros.
