Sort of. My very first family left her home to kick off the legacy family. The game play was pretty much a rags to riches play through except my sim was in debt because they bought an empty 64x64 plot of land and they needed to pay it off before they could start building or having any kids. That 64x64 lot is meant to stay as the "legacy family" land no matter what happens in my game.
I play with death on, but lifespans set to long.
Currently my heir to this land is in college, I make it a habit to follow wherever the heir goes, and while I do try to complete some story arcs for other members of the family, everything I do must work around the heir's life. For example, the heir is going to do campus for their 2nd,3rd and 4th year of college and I am going with them, so I need to get everyone's life where I want it before we leave for college.
While at college, the only remaining family in the household passed away, and the game gave away all of animals and since no one is there to care for the land during the last year in college, I decided to have the land get caught up in courts (We don't have a job and can't afford the land right now), so now my sim needs to live elsewhere until the courts finish the inheritance paperwork and we can afford to pay the bills on that land.
So the land plays an important role in my legacy, some traits may cause them to lose the land, and then the next generation will try to get it back b.c its important, others may live someplace else until they feel they can inherit, or some may just live somewhere else until their parents die and they take over. I bounce around in the places I live to keep things fresh, but I also remodel the land for some families.
I don't know how you play or what you like, but you can move families around and boomerang back to the "main family" home like I do, or you can keep them grounded, or you can have them move for every generation, whichever you find more enjoyable to play.
