FlamingoKicker There is a time limit on how long a ghost will remain in the game before being culled. That time limit is 90 in game days. Using the Strengthen option on the urn/tombstone will reset the counter and extend the time another 90 days. You can do that as many times as you like. Basically, if you look at an urn/tombstone and it still has the Strengthen option, then the ghost is still in the game. If the option is no longer there, then the ghost has been culled. It does take a while after a sim dies before the option shows up on the urn, so a player needs to keep checking the urn until the option appears.
In your case, Alexander and Cassandra died more than 90 days ago and have been culled from the game. Once a sim has been culled, there is no way to get them back short of loading new copies of them from your Library or the Gallery. However, they will be different sims and not have any familial connections to other sims as well as only having skills, etc. that they had at the time you saved them to your Library.
Hope this helps.
