John Doe, III is an example.
Name Here III
III is the Roman numeral for three, if it appears after the name of a King or Queen, for example King Richard III, it would be read as King Richard the Third.
The correct way to write the name is "James Smith III, MD." In this format, the first name comes first, followed by the last name, the generational suffix (III), and finally the professional designation (MD) for medical doctor. It's important to place the title "MD" after the full name for clarity and proper convention.
Last Name, First (Given) Name, III
You would write their name followed by "III" to indicate they are the third person with the same name in their family. For example, John Smith III.

Marshall Bruce Mathers III
Brown, Robert J. III
you put the before and after
Rush Hudson Limbaugh III
Just III, like you wrote above. (If you were to speak the written name, you would say, for example, "John Henry Smith the third".)
