1927

Jack Harkness landed on Ellis Island in 1927. His forged visa was stolen by Angelo Colasanto. Angelo was imprisoned, but Jack faked papers to let him out. Jack and Angelo eventually found a room to share in New York City. They thwarted a plot by the Trickster's Brigade to use an alien parasite to harm future US President Franklin Delano Roosevelt's mind and allow the Third Reich to win World War II. Jack disintegrated the creature, but was caught by the police. Jack was shot and Angelo arrested. He assumed that Jack was dead. (TV: Immortal Sins)

Also sometime during 1927 Mary Baker, the future paternal grandmother of Julia Hardwick as well as one of her possible descendants due to time travel, was born. (WC: A Ghost Story for Christmas)

Alternative timeline

 * December - In an alternative timeline accidentally created by the Fifth Doctor, the RMS Lusitania did not sink on 7 May 1915 and a petty criminal named Eric Charles Vincent (who died in the sinking of the Lusitania in the proper timeline) killed Alexander Fleming in a botched robbery attempt before the biologist discovered penicillin. Without the protection offered by penicillin, Earth fell prey to new strains of meningitis and pneumonia in 1956 and the survivors never developed a space programme. Consequently, the Knights of Velyshaa were not defeated by the Earth Alliance in 3562 as they otherwise would have been. (AUDIO: The Sirens of Time)
