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).
I know
but it's not a physical thing
and websites go down as fast as they go up
that's why I would like to make something that would last for generations
