Gideon was born into the wizarding Prewett family, with his two known siblings: Fabian and Molly. During the First Wizarding War, Molly, Gideon's sister, married Arthur Weasley, and the couple eventually had seven children. During the First Wizarding War, Gideon and his brother decided to join the ranks of the Order of the Phoenix to fight against Lord Voldemort and his Death Eaters. Their sister does not appear to have been an official member, probably because she had young children to take care of.
Eventually, however, Gideon and Fabian were attacked by five Death Eaters, one of whom was Antonin Dolohov. They were described as having "fought like heroes" by fellow Order member Alastor "Mad-Eye" Moody, though both were ultimately killed. Following Voldemort's fall from power, Dolohov, and perhaps others involved in the Prewetts' "brutal" murders, were imprisoned in Azkaban for the crime.
