Also any fairy tales or poems have tid bits that are good to know. PA Dutch Pow Wow has basically renames Christ for god in the spells they us and it's an interesting read.

The goddess I work with daily is Holda/ Holle. She covers pretty much any task a house wife would be involved in. She will soon start leading the Wild Hunt again.
My son has autism and really can't understand the concept of deity. I don't hide my practice and he knows not to bother the altars but he doesn't participate much in my religion or rituals.
