Has anyone accomplished the Legendary Legacy achievement?

Out of all the bugs and problems with the game, repairing the genealogy and family tree is the most important in my opinion. It even places higher than "toddlers". What is the point of adding another dimension to the game with another life phase if the individual will soon disappear as if they never existed at all? Sure, toddlers would add so much to the game, but we would simply be loosing more as well when those Sims are gone.
