Normally the III means that "John Doe III's" father and grandfather are named (grandfather) "John Doe Sr." and (father) is named "John Doe Jr.". Which would change their names to "John Doe I" and "John Doe II" when "John Doe III" is named. The naming can also skip a generation or even a nephew or grandnephew can continue the name. I have seen the use of the roman numeral system with female names also.
