 The Druidic concept of ancestry is that of "ancestors of the land", rather than the "ancestors of the blood" venerated by some Heathen groups; they perceive a spiritual connection, rather than a genetic one, as being important.Emphasising ancestors gives practitioners a sense of an identity which has been passed down from the past over the course of many centuries.Ancestor veneration leads many to object to the archaeological excavation of human remains and their subsequent display in museums.
