Martha Jones

Dr Martha Jones worked as a medical student at the Royal Hope Hospital in London when she first met the Doctor. Eventually, after deciding to leave him, the Doctor ensured that she would find work with UNIT.

Family
Martha's parents were Francine and Clive Jones. She had an older sister, Letitia "Tish" Jones and a younger brother, Leo, who lived with his girlfriend and had a child. On the day that Martha first met the Doctor, her family had a row at her brother Leo's 21st birthday due to Clive insisting on bringing his young girlfriend Annalise, much to his estranged wife's disgust. (DW: Smith and Jones) Martha's cousin, Adeola Oshodi worked at Torchwood 1 before her death (DW: Army of Ghosts).

Joining the Doctor
The twenty-three-year-old Martha was working at Royal Hope Hospital under Mr Stoker when she encountered the Doctor. She encountered him on the street, then gave him a cursory physical (and learnt that he had two hearts) and later helped him defeat the Plasmavore "Florence Finnegan" when the hospital was transported to the Moon by the Judoon. That evening, she joined the Doctor on his travels. The Doctor insisted, however, that he had not brought Martha aboard the TARDIS as a replacement for his previous companion, Rose Tyler. (DW: Smith and Jones)

After returning home in The Lazarus Experimentrus Experiment]], the Doctor asks her if she wants one more trip in the TARDIS but she refuses, saying that she doesn't want to be a passenger anymore. The Doctor allowed her to stay on board the TARDIS, stating that she was never "just a passenger". He gave her a mobile phone upgrade and a TARDIS key (DW:42).

Time away from the Doctor
When the Master took over Earth, Martha pretended to make a weapon that would kill the Master. She said that she had witnessed the Toclafane burn the islands of Japan. She spent a year on earth telling everyone to think of the Doctor at a specific time so that the Master could be defeated. This plan worked and the Master was shot by his wife Lucy Saxon. As a result of the destruction of the Master's Paradox Machine, only Martha, her family, and everyone else who was on board the Valiant remembered that year spent with the Master. She decided she wanted to go and complete her medical studies, but gave the Doctor her enhanced mobile phone, saying that she might want to return to travelling with him in the future. (DW: Last of the Time Lords)

Joining UNIT and short tenure with Torchwood
The Doctor put in a good word for Martha at UNIT. At the request of Captain Jack, as a UNIT, she visited Torchwood 3 in Cardiff, where she became embroiled in their investigation of a private medical organization called The Pharm. Torchwood sent her into the Pharm as an undercover agent, but during the course of her investigation she was discovered and captured and the Mayflies were put into her body. Owen Harper saved her life using an alien surgical device but Alan Copley killed him. Just as Copley was about to shoot Martha he was shot in the head by Jack Harkness. (TW: Reset) Martha witnessed Owen's return from the dead as an undead being means of the resurrection gauntlet and gave him a posthumous physical. "Death", a force possessing Harper aged Martha into an old woman. After the Death being vanished, she reverted to normal (TW: Dead Man Walking) She mended Harper's injured hand after, in a fit of self-destruction, he deliberately wounded it, after Jack decided to relieve him of duty at Torchwood. When Owen Harper was promoted back to Doctor, she left for UNIT, a few days after she had joined on (TW: A Day in the Death). She didn't go to Gwen Cooper's wedding because of work (Torchwood website).

Back at UNIT, her boyfriend, Thomas Milligan and Martha got engaged (DW: The Sontaran Stratagem), though he left Britain for a while to go to Africa (DW: The Poison Sky)

Reunion with the Doctor
Martha called the Doctor just as she, together with UNIT, was about to attack the ATMOS factory which secretly formed a key part of a Sontaran invasion plan. At the time, she worked under the by-the-book Colonel Mace who was in charge of the operation. Later that day she warned Donna Noble to keep her family safe because of what had happened to her own family at the hands of the Master. A few minutes later she was kidnapped by two solders under Sontaran control and taken to her to a cloning pool, where they started copying her body. She then was put to sleep but kept alive as a her clone was about to aid the Sontarans and needed access to her memories. (DW: The Sontaran Stratagem) Martha's clone died soon after the Doctor rescued the real Martha. While chatting with the Doctor and Donna inside the TARDIS after the defeat of the Sontarans, Martha turned down the Doctor's offer to let her travel again with him. As soon as she had made her refusal unknown force took control of the ship and dragged it into the Vortex (DW: The Poison Sky).

Martha walked out of the Tardis onto the planet Messaline, remarking to Donna that even though she didn't want to travel with the Doctor any more, she loved the first steps of exploration on a new planet. On Messaline the Doctor was immediately taken hold of and his hand put in a machine to form his daughter, Jenny. Soon after, they were attacked by the Hath. Martha was separated from the Doctor and Donna and taken by the Hath. She saw an injured one named Hath Peck whom Martha helps, earning the Haths' trust, who then showed her a map of where they are. The Doctor was shown a corresponding map, and caused new passages and tunnels to appear on both maps, much to the Haths' surprise, who think Martha was responsible. The Doctor then called her, and told her where they were heading. Martha found a way onto the planet's surface and took Hath Peck with her. On the surface Martha slipped into something like a pool of quicksand, but Hath Peck saved her life, sacrificing his own, to Martha's distress. Martha then saw the temple and was reunited with The Doctor, Donna and Jenny there. They discovered what the Humans and Hath were fighting over; the Source which will make the planet's surface habitable again. As the Hath and the Humans come running up the Doctor released the Source, however General Cobb was jealous and shot at the Doctor, wounding Jenny instead. When the Doctor said that there was a possibility she would come back to life, Martha shook her head and confirmed she was dead. Later, the Doctor took her back to Earth where she cheerfully said farewell to him and Donna, and was reunited with her fiancé, Thomas Milligan (DW: The Doctor's Daughter).

Reunion with Jack
Martha and Jack are rumoured to leave together at the end of Journey's End to join the Torchwood Institute.
