Thanks to everyone for helping me unlock the mystery surrounding the Pieman. I am attaching some additional data I have located in the event anyone is curious. (in order of published date):
The Yorkshire Evening Post - 8 Jun 1897:

The Herald - 11 Jun 1897:

The Leeds Times - 12 Jun 1897:

James Kenny is buried in Utley Cemetery (Section E; Grave 225); Along with his yound daughter Catherine and two other individuals. There is no marker on the grave. James' spouse Annie Eliza (Donigan - spelled many different ways depending on the source) moved the family to Massachusetts not long after his passing where most remained for the rest of their lives. Annie died on April 19, 1948 and is buried in Lawrence, Massachusetts.
Did James take his own life? Did he suffer some sort of injury while an iron worker earlier in life? Which sister is mentioned in the article? Why was she in the asylum?
Any suggestions on where to go next?
