Susan Foreman

"Susan" was the assumed name of a Gallifreyan who was the original companion of the First Doctor, her grandfather. A descendant of Rassilon, Susan travelled with the Doctor and reunited with him in their fifth (TV: The Five Doctors) and eighth incarnations. (PROSE: Legacy of the Daleks; AUDIO: An Earthly Child, etc.) At different times in her life she was known as "Susan Foreman", "Susan English" and "Susan Campbell", but she was usually called simply "Susan". According to some sources, (PROSE: A Brief History of Time Lords) her birth name was Larn (PROSE: Birth of a Renegade) or Arkytior. (PROSE: Roses)

After she left Gallifrey with the First Doctor, records of her true identity were deliberately obscured. She was possibly the daughter of the Lord President, (PROSE: A Brief History of Time Lords) and she was born with a different name than "Susan", (PROSE: Frayed, AUDIO: All Hands on Deck) which may have been Larn (PROSE: Birth of a Renegade, A Brief History of Time Lords) or Arkytior, from the Gallifreyan for "rose". (PROSE: Roses, A Brief History of Time Lords) She may have been a direct descendant of Rassilon or of some other founding father of Gallifrey. (PROSE: Lungbarrow, A Brief History of Time Lords)

Susan specifically identified the Doctor as her grandfather, (TV: "An Unearthly Child", "The Escape") as did Barbara Wright, (TV: "An Unearthly Child", "Hidden Danger") Ian Chesterton, (TV: "The Ambush", "Kidnap") Ping-Cho (TV: "The Wall of Lies") and the First Doctor himself, (TV: "The Brink of Disaster") while the First Doctor considered Susan to be his grandchild, (TV: "The Rescue", Marco Polo, The Sensorites, "Flashpoint") as did the Fifth Doctor, (AUDIO: The Toy) the Eighth Doctor (AUDIO: Relative Dimensions) and the First Elder. (TV: "Hidden Danger") The Eleventh Doctor later recalled coming to the Rings of Akhaten "a long time ago with my granddaughter". (TV: The Rings of Akhaten) The Curator cited his having had a granddaughter as evidence that the Doctor had not been a virgin, contrary to popular belief — thereby ostensibly confirming a biological relation between the Doctor and the granddaughter in question. (PROSE: The Day of the Doctor)

However, other accounts cast doubt on their biological relationship. One, related by the Master, described Susan as Lady Larn, a contemporary of the Doctor whom he had rescued from civil strife on Gallifrey. (PROSE: Birth of a Renegade) Another intimated that she was one of the last children born on Gallifrey before Pythia's Curse, (PROSE: Lungbarrow) with Patience's husband present at her birth. (PROSE: Cold Fusion) She was sent away from Gallifrey by the Other — her grandfather — to Tersurus during the Great Schism. She later returned to Gallifrey to search for him, where she met the Doctor, whom she recognised as her grandfather reborn. (PROSE: Lungbarrow)
