Gillian Who (The Incomplete Death’s Head) was a companion and granddaughter of the First Doctor and his subsequent incarnation.
Gillian and her brother John were originally natives of 20th century Earth. However, after visiting their grandfather in his TARDIS, they were whisked away into adventure. The Doctor attempted to get them home for some time after this, but faced trouble because of the damaged controls of the TARDIS. The two spent much time in his care, and grew from children into teenagers. They eventually gave up on their ambitions of returning to 1964, and enjoyed their adventures across the universe.
At some point, the pair stopped travelling with the First Doctor and began travelling with his rejuvenated incarnation instead. The trio fought Kleptons, Daleks, Cybermen, Witches, and Trods, but when faced with the threat of the Quarks, The Doctor chose to enrol them at Zebadee University so they could be safe without him.
