It's confusing so here goes:If the father's father's name is John Smith and has a son they call John Smith Jr., then it makes the son's father John Smith, Sr.If John Smith Jr., has a son and calls him John Smith, Jr., then it's 'John Smith Jr. II, but if John Smith Jr., calls his son Timothy Smith then there is no Jr. II behind it. Junior is only applied when the first and last name is the same of the father of the child.
When writing a name in last name first format, suffixes like Jr. or Sr. typically follow the last name. For example, John Smith Jr. would be written as Smith, John Jr. and John Smith Jr. Sr. would be written as Smith, John Jr. Sr.
