|Hold it right there, outlaw!|
This article is littered with spoilers, so I reckon you might ought'a mosey on down the road if you don't want to read any plot details.
The known family history only traces back up to John's father, who was born on the boat ride from Scotland to America when John's grandparents immigrated to the U.S. It is said by John that, "If you ever spoke to him, you'd think he only ate haggis and wore a kilt", which implies that he either had a heavy accent, or knew his culture very well. He also hated the English for what they did to his (John's father's) great-grandparents.
It was implied that John's father was his mother's pimp. Not much is known about her, except that she was a prostitute, and died while giving birth to John. Sometime early in John's childhood, his father was "blinded in a bar fight, south of Chicago". When John was eight years old, his father supposedly died in another bar fight. He was then sent to an orphanage.
However, he soon ran away from the orphanage, and eventually met Dutch Van Der Linde, who would take him in and serve as a father figure to him (along with Bill Williamson, Javier Escuella, and Abigail Marston). It was Dutch who taught John how to read, and 'the ways of the world'. For a long time, John was an outlaw alongside Dutch, until he was shot, and almost killed during a bank robbery.
Abigail, while with the gang, served as a prostitute, possibly just among the gang and how she met her future husband Sometime before the robbery where John was shot, she would marry John, and become pregnant with their children.
John and Abigail had two children together, John Marston Jr. (a.k.a. "Jack"), and an unnamed daughter, who passed away sometime before 1911. Jack grew up amongst the gang, oftentimes referring to Dutch, Bill, and possibly Javier as uncles. The daughter's name is never told but when John was talking about his family, he said his daughter was taken by cholera.
After the robbery, John gave up the life of an outlaw, and bought a ranch in the Great Plains area called Beecher's Hope. He would hire Uncle, a former drinking friend (and possibly a former gang member,) to help on the ranch. He would also get a dog, Rufus, to help him hunt.
