I tried nursing her back to health, but she must have been just too far gone.

She was only in her 30s.
Their son managed to hang for a few more (VF) years, but kept getting hit with one illness after another, and I couldn't get him past "extremely weak." He died at 14.

I thought maybe the dad would get a matchmaking email, giving him the chance to remarry and have more kids, but he's 53 now and it hasn't happened yet. He keeps sending me emails telling me how lonely he is, I feel so bad for him!
So now what happens when my final peep dies? Because their only offspring is deceased, the "Next Generation" option isn't available on the Details page. It was there after his mom died, but when he died it went away.
