I feel like the VAST majority of them would go unobserved. Maybe it could be request driven? No sense converting thousands of family histories if only a small fraction will ever be looked at. Would that be possible? Maybe in Information under Global, a request button, and you submit the family name you are looking for?
As for how it should look, I think probably the same as current family histories are laid out. It is familiar already.
How are they stored currently?
