Problem here is that the family home is often irrelevant to the family. Take my family for instance. My family home is on the colonies, I graced the realm of my first character for all of 3 hours before deleting the character and creating a viking. As the only input you have about your family home is a random region in the first realm you join, which lets face it for new players is mostly just a random choice, family homes have much less impact then they could.
Sure you can move family homes with a Hero, but that very feature undoes the "history" aspect anyway.
And I've known a few that go out of their way to become lords of their home region and maintain close ties to it, including myself. Guess it depends how much of a RPer someone really is.
