The current beta version of Ancient Savo has three starting scenarios. One of them is "leave everything behind", while the other two include the previous generation so that you actually start at the home, the parents still alive.

Today I've been adding one more generation to the chain, so that in addition to your parents there is also a family burial site, with the grandparents buried there. Currently there isn't any real way to interact with the spirits of the late ancestors, but it is possible to switch playing as the spirits. In that mode you can't control the game, you just watch the AI run the living members of the family. I'm not yet sure, but I'm feel slightly optimistic about adding some interaction between the spirits and the living - once some other more urgent features are implemented.
