Le Lapin was born in the spring of 1860 in a large city in coastal France; the illegitimate son of a prostitute. His father, a man he never knew, was rumored to have gone mad and shot himself, and his mother died of fever when he was young. He grew up and was raised by his older siblings in a cramped tenement along the port.
Restless, disruptive, and quick to fight, he was considered burdensome, and was sent to a religious boarding school outside the city. Despite struggling at first, he gradually adapted to its rigid structure. He was a surprsingly intelligent student, if sometimes disobedient and cocky. He formed a small circle of friends, who nicknamed him "Le Lapin" for how fast he could run and his big ears.
Just before he graduated, he dropped out to care for his younger sister who had fallen ill. Meanwhile, his eldest brother began spending money they didn't have on drink. He rarely came back home, leaving Le Lapin responsible for the household. After his sister's death, an argument broke out. His drunken brother insulted and taunted him for his wasted efforts. Knowing he was right, Le Lapin chocked him in anger until he turned blue. Panicked and alone, Le Lapin hid the body and fled. He reached the docks and hid aboard a merchant ship. However, by the time he woke, the vessel had already departed.
After being discovered, shortly before reaching
New York, he escaped before authorities could take him. Terrified, he took himself a loose horse and pushed west for nearly half a year. Desperate for money, he eventually sold it and tried to head west by slipping onto a train, but a rail patrol dragged him down before it departed. He was locked up on a vagrancy charge, but managed to slip out and flee only a week later.
After escaping custody, he acquainted himself with a settler family making their way west on a wagon, who allowed him to ride along. The children spoke better English than their parents and taught him on the way. However, with his usefulness concluded after they reached the
Dakotas, his paranoid frenzy continued, and he slipped away with one of their horses and continued west alone.
By late winter he reached the
Montana Territory, hypothermic and exhaustion. He rode until his horse collapsed beneath him. He would likely have died there if not for a passing preacher, Reverend Glasseye, who found him and carried him to shelter.
