Toynbee "Sìlvio"
Silvius, posthumous son of Aeneas by Lavinia, daughter of Latinus, king of Latium; according to the account given by Servius (on {Aen. vi. 760}) Lavinia, being left with child at the death of Aeneas, took refuge in the woods for fear of Ascanius (Aeneas' son by Creusa), and there gave birth to Silvius; it was then arranged that Lavinia should have Lavinium, while Ascanius founded Alba, in which kingdom he was eventually succeeded by Silvius.

D. refers to Aeneas as di Silvio lo parente, [Inf. ii. 13] [Enea]; and follows Virgil in making Silvius the son, not of Ascanius as some do (e.g. {Livy i. 4}), but of Aeneas:

Silvius, Albanum nomen, tua postuma proles,
quem tibi longaevo serum Lavinia coniunx
educet silvis regem regumque parentem,
unde genus Longa nostrum dominabitur Alba.
({Aen. vi. 763-766})
