Marriage

Marriage was the union of persons. It was usually made formal by a wedding service.

After Amy Pond and Rory Williams were married, Amy remembered the Eleventh Doctor back into existence. (TV: The Big Bang)

The Trickster arranged for Sarah Jane Smith to meet and fall in love with Peter Dalton. Once they were married, she would forget about defending the Earth and the Trickster could feed on the chaos. Peter revoked his deal with the Trickster, thus defeating it. (TV: The Wedding of Sarah Jane Smith)

(TV: Last Christmas) Earlier in her travels with the Doctor, Clara received a wedding proposal from Emperor Ludens Nimrod Kendrick Cord Longstaff XLI (a.k.a. "Porridge"), but she declined his offer. (TV: Nightmare in Silver)

Several of the Doctor's companions are known to have married following their travels with him. Examples include Peri Brown marrying King Yrcanos; (TV: The Ultimate Foe) Martha Jones and Mickey Smith; (TV: The End of Time) Ian Chesterton and Barbara Wright; (TV: Death of the Doctor, COMIC: Hunters of the Burning Stone) Ben Jackson and Polly Wright; (TV: Death of the Doctor) Jo Grant and Clifford Jones; (TV: The Green Death, Death of the Doctor) and Vicki Pallister to Troilus. (TV: The Myth Makers) By the time he encountered the Seventh Doctor in the 1990s, Brigadier Lethbridge-Stewart had finally married his longtime girlfriend, Doris. (TV: Planet of the Spiders, Battlefield)

The Doctor was known to have been married at least four times. (TV: Death in Heaven) This list included Scarlette, Elizabeth I, Marilyn Monroe, Cleopatra and River Song. (PROSE: The Adventuress of Henrietta Street, TV: The Day of the Doctor, A Christmas Carol, The Husbands of River Song, The Wedding of River Song) The Ninth Doctor once implied he married Lady Mary Wortley Montagu for love, but left it ambiguous. (PROSE: Only Human) River engaged in polygamy during her marriage with the Doctor, marrying Ramone, Stephen Fry and King Hydroflax, though the marriage to Hydroflax was part of a scam to retrieve a rare diamond he contained within his body armour. (TV: The Husbands of River Song)

The Aplans engaged in self marrying until the church enacted laws against it. (TV: The Time of Angels) River Song also stated she married herself on every planet where self marriage was allowed. (AUDIO: Someone I Once Knew)

In some times and places, rules existed as to who a person was allowed to marry. In the United States in 1969, marriage between humans of the same sex was disallowed, while marriage between two humans of differing race was frowned upon. President Richard Nixon was willing to allow Canton Everett Delaware III to marry his black partner, but quickly changed his mind upon learning said partner was a man. (TV: Day of the Moon) These restrictions were near nonexistent by the early 21st century, at least in the United Kingdom; Donna Noble, a white woman, was set to marry Lance Bennett, a black man, before he was revealed to be in league with the Empress of the Racnoss, (TV: The Runaway Bride) and Laura, a friend of Amy Pond, became engaged to her girlfriend during the The Year of the Slow Invasion, and were married the following June. (TV: The Power of Three)

Behind the scenes
Although there have been many occasions in which married couples have been involved with Doctor Who and related productions in front of and behind the lens or microphone, a few real-life marriages worth noting include Jon Pertwee and Jean Marsh (who were married in the 1950s, years before either appeared on the series); Tom Baker and Lalla Ward (who wed during a break in production on TV: The Keeper of Traken but divorced a year and a half later); and David Tennant and his TV: The Doctor's Daughter co-star Georgia Moffett (also the daughter of Peter Davison). Caroline John was also married to Master actor Geoffrey Beevers until her death.
