Use the following guidelines when indexing names with a suffix
Any suffix should be entered after the last given name.
No comma should be entered between the last given name and such suffix.
Any suffix word should not be actively abbreviated
If the suffix is not presented as an abbreviation but is presented as a complete word and the suffix is not setoff by a comma, two entries should be made. Once with the suffix as the surname and once with the suffix as a suffix.
A suffix is frequently encountered which indicates family lineage. Some examples of lineage suffixes are:
JR.
SR.
II
III
JUNIOR
SENIOR
This simply states that any such suffix be entered following the last given name and that no comma should separate the given name and the suffix. Additionally, no such suffix should be actively abbreviated at any time. If the suffix is not presented as an abbreviation and the suffix is not separated from the name with a comma, two entries are made: (1) with the suffix as a suffix, and (2) with the suffix as the surname. No assumption should be made that the apparent suffix is indeed a suffix in this instance.
Name presented: William John Smith, III
Would be indexed as:
SMITH, WILLIAM JOHN III
Name presented: John Andrew Simmons, Junior
Would be indexed as:
SIMMONS, JOHN ANDREW JUNIOR
Name presented: Dan Alexander Roberts Junior
Would be indexed as:
ROBERTS, DAN ALEXANDER JUNIOR
JUNIOR, DAN ALEXANDER ROBERTS
Since there is no comma (,) following the name ROBERTS in the above example then we must enter the name twice, once with ROBERTS as the surname and once with JUNIOR as the surname.
