According records, he went to prison in 1914 for cattle rustling and spent 18 months in the Nevada State Penitentiary. This first extended period of thinking helped encourage his concentration on drawing.
James wasn’t born in Montana as he told his jailers in Nevada. In fact, he wasn’t a Westerner at all, or a U.S. citizen, or even a native English speaker.
Will James was baptized Joseph-Ernest-Nephtali Dufault in French-speaking Saint-Nazaire-d’Acton, Quebec, Canada in 1892, where his father was a merchant.
The truth about him was revealed twenty years after his death by his biographer, Anthony Amaral.
James left home at age fifteen and headed West, first to Saskatchewan, then Montana. He was indeed a cowboy and was a popular and cheerful camp mate and a gifted story teller around the evening camp fires. His cronies affectionately called him "Windy Bill" for his talkativeness and ability to spin a yarn.
