RegX problems

[otuatail]

<?php
// Library SMS3S Version 1.0.0   15-03-2014 
include ("../secure/SecureFunctions.php");
session_start();
Session_Init();

$name1= "O'Brian"; // Match O' if second character is (')
$name2 = "Robinson";

$myReg = "/(O')[A-Za-z]{12} | [A-Za-z]{14}/";

if(preg_match($myReg, $name1))
   echo "Yes";
else
   echo "No";

echo "<br><br>";
  
if(preg_match($myReg, $name2))
   echo "Yes";
else
   echo "No";
?>

I am trying to put together a simple surname match with a slight difference. Any help on RexX?
