Actually, Aeneas was supposed to have married a Latin Princess, Lavinia, who came from a place called Laurentium and was the daughter of King Latinus. His son supposedly founded a city called Alba Longa from which Romulus and Remus have come. Alba Longa did exist. It was destrooyed by the Romans in an early war and its population incorporated into Rome. Some Net site I was on said they think they have found the cemetary for Alba Longa, but there are no ruins yet located. It was near the Alban Lake.
Thanks for the information. A few more pieces of the puzzle have fallen into place.
