Question about the Hebrew name

Just one question,I’m not Jewish and I’m not in the process of becoming one, but I had a question about names in Hebrew.

I’ll give you my own example. My name is Gabriel, so logically my name would be Gavri’el (correct, right?). My mother’s name is Eliana, which has its Hebrew version, but my father’s name, Sergio, has no translation. What would the name be? (Considering, of course, that neither of them are Jewish and they don’t have the Hebrew name)

I think it would probably be Gavri’el ben Avraham, because my father is not Jewish and does not have a Hebrew name. But what about my mother? Would I put Sarah or would it be Eliana?

Sorry if I said something wrong. I’m very new to the community and I still have a lot to learn
