The matriarch/patriarch usually stay in one place, but I definitely move out most of the kids, definitely the ones I plan on continuing to play. Maybe one child (the youngest?) stays at the original homestead to take over the place eventually, but I do move out other siblings so they can start new lives. Some siblings, depending on my goals, may get shipped off to apartments in San MyShuno and then changed to unplayed so I don't need to deal with them anymore, but most I usually try to play rotationally, depending on what I'm trying to achieve. That next generation may or may not stay in the same place they originally moved to. Sometimes they outgrow the place with their own kids, or sometimes I just find I don't like the lot after playing with it for a while so they move because of that.
