I wonder if this is an XY problem. Do you have a list of people, and you think some of them are duplicates (i.e., "James Brown" and "Jim Brown")? In that case, I don't think you can be sure that they're really duplicated and not just two people with similar names (or even identical names). If you don't have some other way to uniquely identify them, you're just guessing.

Update: For a practical example of this problem in action, see here.
