How do I site an author with a roman numeral?

[kirstielovesyou]

James A. Largay III, to be exact. Where does the "III" go?

Use a comma after the last name. III is a suffix, just as Jr. or Sr.

James A. Largay, III

 

[Andrew L]

Largay, James A., III

(put the numerals at the end after the initials).
