Both couples died together and they had only one child. She was 14 when they passed and I decided to keep her around for a bit just for kicks. Well she is 18 now and sent me and email saying that she is enjoying being married. Of course she did not get a proposal. Surely this is a glitch... has this happened to anyone else by chance?

Sure looks like a glitch. Does she show as married or single in the details screen?

Strange... maybe she's saying she is lonely?
