1.) (Fictitious character) In the Lincoln's White House Mystery series by C.[Colleen] M. Gleason, Adam Quinn is a nephew of Lincoln's close friend, Joshua Speed.
His father died in a fall from a horse when Adam was 7, and Adam found the body. When his mother remarried, the blended family was rather large, and Adam was sent to live with his uncle, Joshua Speed, in Springfield, Ill.
When Adam grew up, he lived with the Ojibwe for 5 years, his particular friend being Ishkode, who taught Adam tracking. When free land was available in Kansas, Adam went there. During the wars over whether Kansas would be a free or slave state, Adam was shot and lost his lower arm. He has a prosthesis.
In order to keep Adam occupied and helped him deal with the horrors he had seen in "Bleeding Kansas," his uncle Joshua got his good friend Abraham Lincoln to hire him as a general factotum. Adam made himself useful, but intended to leave after Lincoln's inauguration. When Custer Billings is murdered at the Inaugural Ball, Adam is asked to lead the investigation.
