I'm thinking of creating a physical family tree I could hold in my hands
However I would like to be able to pass it on, so information could be added on later (trough generations)
Any ideas how this could be done?
From my experience, the best was to do this is to make family tree online, on specialized services (like myheritage).
In this way, many pother people can find you online, your possible relatives or descendants, your data will never be lost and your family tree anybody can edit (if they have some info about your family tree).
