As I understand it, Victoria Winters died in 1795 (or 1796, or 1797, depending on the writers) as the result of something done by Jebez Hawkes. I don't think any time traveling happened to undo that. She was supposed to be revealed as Elizabeth's daughter, but near the end of the Adam storyline she was pregnant and left he show. It was really too bad because she was such a beautiful woman and amazing actor.
