When did Dorothea Camden die?

Dorothea Camden, the matriarch of the television show "7th Heaven," was never shown to have died on the show. The character of Ruthie Camden (played by Mackenzie Rosman), the youngest of the Camden children, was the one who passed away in the series finale.

It's important to note that Dorothea Camden was a fictional character and her death was never portrayed in the series.
