According to my grandfather, Hugh J. Staton, he rode with Quantrell during the war and was with Quantrell at the Lawrence raid.
I know that my grandfather came out to California from Oklahoma prior to the dustbowl and that his father and mother followed (along with Sam) a few years later. They settled in the (at that time) sleepy town of Santa Ana, California where my grandfather was self employed in a number of activities, finally owning and operating a number of filling stations.
There is one story about Sam that I remember distinctly:
While living in Santa Ana, He used to go to get his haircut at a particular barber. Evidently (unknown to Sam)a former Union cavalry officer did as well. On one day they both arrived at roughly the same time.
A lively "discussion" ensued, ending with the former Union officer unconscious on the floor. Sam was required to make an appointment after this. Sam Kimberlin was in his 70's when this happened.
I hope this information is helpful. If you have anything to add regarding his earlier life, I would be grateful to hear it. Me grandfather and father held him in very high regard.
