Proper nouns are not usually translated, even when they have equivalents in a foreign language. For example, my English name is Stephen King. In Spanish there are equivalent names Stephen = Esteban, and King = rey. But my name in Spanish is not Esteban Rey, it is still Stephen King. So if you are translating Farsi to English, a person's name should only be written phonetically in the English alphabet so it sounds like the words as written in Farsi. Make sense?
