In this play, a name is very important. Does a person's name influece your opinion of that person?

In my opinion, a person's name really doesn't influence my opinion of that person. It is true that depending his or her name, before knowing about that person, you can have an idea of him or her. For example, if that person's name is Jack you know that probably he lives in USA or United Kingdom, so you know that, he/she speaks in english. That means that if you don't like american or english men, maybe you won't want to know about him. But in general a person's name doesn't influece my opinion, for me his/her behaviour and the way that he/she comports with me is more important. Can someone explain his/her opinion?
