It appears as if the mother of the child is not named and her parents unknown? I am assuming there was no marriage as well?

Maybe the following image confirms my suspicions.....

You are correct, in the first document Stefano Licata declares that Leonardo was born (16 May 1883) to an unnamed woman with whom he had a relation (no marriage), he also specifies the woman was not married and was not related to him.
According to second document Leonardo died on 30 Oct 1884, at 1 year age, son of Stefano Licata and mother unknown.

They, surely, didn't have a civil marriage, but it's possible that they had religious wedding before that birth. It's also possible that you can find their civil marriage in a following period, with the explicit recognition (acknowledgement?) of the children born during their relation (often only the living children).

Thanks, Livio and Luca. I have found a civil marriage document such as Luca mentioned with an ancestor from Belmonte in which the children from the relationship are named and confirmed as legitimate offspring of the father.
