Thanks Dodi! I did have a copy of the whole family in the Gallery so I was able to retrieve them, but I lost a LOT of time. The older son's daughter is a baby now. She had just aged up to teen in the original game. Oh well. At least I have the whole family back now.
I would now like to know how to eliminate 1 sim. The younger son, in my original game had already gotten married, moved out, and has a couple of children of his own. I really don't want a duplicate of him and besides that, I only have 1 of the lady that he married. I would like to eliminate the original sim and stay w/the one who is married and his family. I hope this makes sense, lol
