The issue you might be facing is much of what you are seeking has been passed down in oral history & may be closely guarded, or lost from those who had the knowledge being persecuted.
The oak was a symbol for the Norse, celtic,Hebrew & druids.
Crows are found in Chinese, Scandinavian and native American lore.
Mists lore are often greek in origin.

Yes, I think you're right.
I had a resource that took something like the oak and discussed it in terms of Norse, celtic, etc. Our librarian, however, purged the shelves and eliminated the book. I was hoping I could find something similar online but I'm struggling.
Some libraries are set up that you can borrow the books on line using a free downloaded Kindle on your cell, tablet or laptop. You just need a library card.
Amazon also has E-books.
Another option is visit your local university and see if the history text books may have what you need.
Do you know what culture you want to study?
@KathMcGill
The students are reading a YA book whose author expertly plays off the symbolic meaning of certain elements like the oak, etc. The students don't need the knowledge to follow the plot, but having the knowledge adds depth to the reading experience. It's one of the few pieces I have for this level that does this--that the students can actually appreciate the craft of the writing process. I wanted to give them the info of the symbolism so they can determine for themselves
