What you are talking about is very similar to the question, "PerlFAQ 4: How can I remove duplicate elements from a list or array?," which I think suggests methods you may wish to look into.

(Personally, I tend toward: 

{
  my (%names);
  foreach (@Person) {
    $names{$_}++; 
  }
  @Person = keys(%names);
}

-but that's just me.)
