Will was born on the Traylor Ranch, raised on the Traylor Ranch and attended school on the Traylor Ranch. In 1910 his family moved to Bloomington which, at the time, was on the Traylor Ranch. In the early twentieth century the ranches in the Coastal Bend comprised a large part of everyone's lives. His parents and both sets of grandparents worked on the Traylor Ranch their entire lives. Will started riding as a ten year old and by sixteen he was working as a cowhand. He loved to hear the cattle “lowing”. He said “some of those cowboys loved to hear the cattle lowing so much they made their beds outside”. Will was the prototypical cowhand in the Coastal Bend, working on all the big ranches - the Terrell, the O’Brien, the Power, the O’Connor and the Welder. The title of Louise O'Connor's first book, Cryin' for Daylight, was pulled from a Will King quote.
