Book recommendations please?

Hello all you lovely people! I'm needing some book recommendations.

I've been interested in practicing witchcraft for about a year, but I've really only started this past month. It's been very spiritually relieving, and I'm so glad I decided to finally start studying and practicing.

My main focus has been green witchcraft thus far, but I want to branch out some. I want to start studying folk magick, specifically Appalachian and German folk magick (those are my family roots). Some history and spells on those subjects would be nice, but I can't seem to find a good book on either. Any and all recommendations are welcome. Thanks all!
