title: Excel [VBA] find duplicate data and delete the oldest one
body: <p>I have a problem in MS Excel. I´ve a spreadsheet with data like this:</p>
  
  <pre><code> Name     |     timestamp
   ------------------------
   Smith    | 12.05.2015
   Smith    | 01.01.2015
   Smith    | 10.05.2015
   Simpson  | 14.04.2015
   Simpson  | 10.02.2015
   Simpson  | 21.03.2015
   Simpson  | 02.01.2015
  </code></pre>
  
  <p>The data I´ve is much bigger and komplex and there are duplicates with different timestamps. Now I want to delete the oldes ones and want an output like this:</p>
  
  <pre><code> Name     |     timestamp
   Smith    | 12.05.2015
   Simpson  | 14.04.2015
  </code></pre>
  
  <p>I know how to remove duplicates, but in this case it´s a little bit different. I hope you can help me to solve the problem.</p>
