This is a really good question and one that I have wondered about myself. But since there is no real records I guess we are at the same place as those folk in the way ancient time, and the answers above that make this statement are probably the most accurate. I'm just going for it and I am thankful that I at least have some names of the ancient gods and goddesses to call out from the new hedgerows!

Maybe it's not so important to go beyond a genuine and sincere approach to the work and just do it. Good luck in your search, I think the journey is the important part anyway.
