Lots of people have ghosts of the ancestors haunting the family home. I kept mine on a separate lot across the street and it became the family cemetary, but it was still a public lot. Once my 10th generation was born, though, the challenge is over. So, now I can do whatever I want with my 10 generation family. So far, I've resurrected two more ghosts. I plan to bring back the entire blood chain through all the generations. What I mean is, all the ancestors who are the direct blood relation to the 10th generation heiress will be brought back to life. I'm just waiting on the opportunities from the science lab. I'll feed them ambrosia and/or life fruit as long as it takes for me to have a Sim from all 10 of the generations alive in Sunset Valley at the same time. Can you imagine?? Lol.
