The answer to this question depends on which version of the story you are referring to.
In the original "Jepperd" story, written by Zane Grey, the character Jepperd does not have a son. The story focuses on his adventures as a rancher and his relationships with other characters.
However, in the "Jepperd" television series that aired in the 1960s, Jepperd does have a son named Mark. The series explores the relationship between Jepperd and Mark, and how Mark learns to navigate the challenges of being a rancher's son.
Therefore, whether or not Jepperd found his son depends on which version of the story you are asking about.
