holidays.el appends holiday-local-holidays to calendar-holidays 
via a defcustom, so if you set holiday-local-holidays in your 
.emacs, restart emacs and the local holidays are not in 
calendar-holidays, it is because you are calling something that 
loads holidays.el before you set holiday-local-holidays.

If you add the code above to your .emacs and later modify your 
configuration and remove or move the part that loads holidays.el, 
then either your code will fail (because calendar-holidays is not 
yet defined) or calendar-holidays will have your local holidays 
twice and they will show twice in your agenda.

I think that you should look for whatever calls holidays.el and 
set holiday-local-holidays before that.

If not, then at least use eval-after-load so that 
calendar-holidays is already defined when the code is run, and 
add-to-list so that the entries do not get added twice if they are 
already there:

#+BEGIN_SRC emacs-lisp
 (eval-after-load 'holidays
   '(dolist (holiday holiday-local-holidays)
            (add-to-list 'calendar-holidays holiday))
#+END_SRC

Best,
