Annalisse

In one of the infinite parallel universes of "possible space", (COMIC: Fire and Brimstone) the Doctor's mother was a "simple", human "peasant-girl" called Annalisse. Ulysses, an early Time Lord and Time Explorer, gave up his immortality to be with her. However, their hybrid son, whom they were raising on Earth, died his first death under tragic circumstances, and, after regenerating, he was sent to Gallifrey, raised as an orphan with no knowledge of his true parentage.
