Is there an etymological (and hence historical) relation between Aeneas's son Iulus and Iulius Caesar? Virgil was obviously trying to establish a conexion of blood, be it mythological, between the gens Iulia and Ilos, but is there any evidence that he did not make this up?

Another possibility is that there are three people with a similar name, the Trojan ancestor Ilos, the Alban Iulus, and the Roman gens Iulia?

What triggered this question is the fact or strong hypothesis that [*Iulus* contains three syllables][1], where the i is vocalic, whereas the first i in *Iulius* is consonantal (/j/).
