First of all thank you for your time! I have a list of names of managers of U.S. mutual funds by fund and year. The problem is that when fund secretaries submitted entries to the database (I am imagining), one year they write "Jim" Last and next year "James" Last. Also, sometimes they make simply a typo: "Jin" Last. (Often typo's are e->c - I would guess that an OCR read the printouts or scans?). It is very unlikely that there would be two fund managers among about 10,000 fund managers with exactly same name, especially when their last name is not a common one. Sometimes there are such cases - for example "Jr." and "Sr." in family-managed funds, but I am either aware of these cases, or can tolerate some errors. Typos and nicknames are much more often and constitute a much bigger problem. Thanks again.
