It is possible that a person could be listed more than once in the People table (which is normal in this particular situation). The probem is I need to have only one final record output to the cursor for each person - so I can print Mailing labels - one per person.

You can run your first select, then select distinct from it. Otherwise you have to group by People.PeopleID and each field except for ID should be some aggregative function, like min, but the result may be incorrect in such case...
If it's not broken, fix it until it is.
