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. (PROSE: The Chronicles of Doctor Who?)

When realizing the shifting nature of his own past, the Infinity Doctor found he contradictorily remembered both Annalise and Penelope Gate as having been his human mother. (PROSE: The Infinity Doctors)

Behind the scenes
Annalise is named after John Leekley's daughter, with characters named "Annalisse" appeared in several of his scripts. In Fathers and Brothers, based off of the Leekley Bible, the Doctor's mother is revealed to have died in ancient Egypt serving as a Queen to the Doctor's father Cheops. A further iteration of this story, titled The Time of My Life, featured the Doctor's father marrying a second wife named Anne.
