To my knowledge stromboli is Sicillian. Notice I didn't say Italian. 
Calzones are from those other guys up north.
Your somewhat right but we call them "vota vota". The most common are spinach, olives & garlic; Parsley & buzzonaglia di tonno (light & dark tuna in oil); ricotta, potato, & onion & sausage & broccoli.
