Jonathan Powell or John James (Butler) Powell

I found this picture in a box of old photos with other photos- one similar styled photo was of Ruth Ellen Page Powell who was married to John James Powell.  On the back of the photo (shown below) it said, Jonathan Powell- this photo may be Jonathan Socwell Powell or it may actually be John James Powell.

John James Powell born 29 December 1859 in Payson, Utah.  Died 14 April 1944 in Salt Lake City, Utah.
