His mother left them when he was a child. He grew up under the care of his father. At the age of seven, he went to live and study under Father Ryan at the local Catholic Church.

He interacted with various models of cars as he cleaned them at the church. He worked hard to please his wealthy car owners during their visits at the car wash. He became inquisitive to understand the mechanical nature of any car he came across. He grasped the mechanical systems fast. He taught himself by practically doing things, rather the conventional theory. Car owners volunteered information to his questions.

In 1904, Jones left the confines of the parish at the age of 11. He was employed at a garage in his hometown. He cleaned the garage and continued observing and helping out in mechanics. At the age of 14, Jones became a fulltime mechanic. He became the garage mechanical supervisor the following year. He developed an interest in car racing. He started working on racing cars.
