Born on 27 March 1960, James would have begun attending Hogwarts in 1971, the year he turned eleven. He met Lily Evans sometime during their time in school together, possibly on their first trip on the Hogwarts Express, as remembered by Severus Snape in the canon universe. James was probably sorted into Gryffindor, based on Professor McGonagall's comment that Harry, on the basis of personality alone, was definitely related to the Scourge of Gryffindor. Also during his time at Hogwarts, James would befriend Sirius Black, of the Most Ancient and Noble House of Black.
James would have left Hogwarts around June of 1978. James inherited vast fortunes from his affluent parents, and was able to comfortably support his family without the need for a paying job. James also used his wealth to support Remus Lupin, who was unemployable due to his status as a werewolf.
James and Lily married after leaving Hogwarts, and on 31 July 1980 Harry was born to the couple. Shortly after this, the couple and their infant son rose to the top of Voldemort's list of enemies and they were targeted for death. They were advised to hide themselves with the Fidelius Charm, with James' friend Sirius Black as the Secret Keeper, but Sirius advised James to allow him to be a decoy only, and make their mutual friend Peter Pettigrew the real Secret Keeper, whom Voldemort would not suspect.
However, the plan backfired. Peter betrayed James and Lily to Voldemort, though no one was aware of this except Sirius, who was blamed for the betrayal. Black was apprehended and placed in Azkaban Prison without trial, putatively for the murder of Peter Pettigrew.
