Answer

If it's the "Love Story", all the details are explicable, including the famous name, which would be Oliver Barrett IV.

We want to encourage Hossein and others to quote the contexts for their questions and to say how much work they have done themselves to understand what they are quoting.  So let him come forward with more information before we rush to help him.  We need to encourage self help.  Give people a fishing rod rather than a fish.
