Wendi: Have you considered whether your dough is correct? Perhaps your Grandmother made it with butter, for example. (Either in the dough or in the filling?) Have you tried cinnamon or other flavorings? (Touch of vanilla?)
Although this is a different cobbler recipe than the one you describe. It may help you figure out your ingredients or it may inspire you in some other way. Good luck!
