Herodotus and other ancient writers claimed the Etruscans were immigrants from Asia minor, possibly from the area of Lydia. It's sometimes asserted that they came west in search of metal: they were famous in antiquity for their metalworking skills and (the theory goes) they came from a much more technoiogically advanced area to exploit the resources of the area.
Given the undoubted intermingling of Etruscans and Romans in the early days of Rome, it's not hard to see how this could give rise to the legend of Trojan immigration to Latium.

Even the legends make no such statement. Aeneas and his followers travel to Latium, the area near the site of Rome and mix with the population. Later, Romulus and Remus, of the line of the Kings of the Latin town of Alba Longa found Rome. According to myth, the Kings of Alba Longa are linked to the Trojans.
Julius Caesar's family traced their heritage back to Aeneas himself, and was proud of that link to the God Venus.
