Anwen Williams

Anwen Williams was the daughter of Gwen Cooper and Rhys Williams. (TW: The New World) Gwen initially discovered that she was pregnant with Anwen when Clement MacDonald was able to "smell" her pregnancy. Later, while she was using Torchwood technology to confirm her pregnancy, Jack Harkness put his hand into the machine that Gwen was using, revealing that there was a bomb inside of him. (TW: Children of Earth: Day One)

After Anwen was born, she lived in hiding with her parents in Wales. She visited her grandfather in Cardiff with her parents, where Rhys convinced Gwen not to investigate the miracle, by suggesting that Anwen could live forever. Later, when her house was under attack, she escaped with her parents, Jack, and Rex Matheson before they were all extradited to America on Rex's orders. (TW: The New World)
