Harley married Bessie (maiden name undetermined) before June 5, 1917.  His obituary named Milo Currens as Harley's brother-in-law.  We find no Bessie Currens (or alternative spelling) or likely candidates (sisters of Harry Milo Currens) in censuses prior to 1920.

On June 5, 1917, Harley registered for Selective Service.  At that time he was residing in Canton, Fulton County, Illinois.  His occupation was blacksmith, employer: P. & O. Plow Company.  He was described as being of medium height and build with gray eyes and red hair.

Harley died on November 14, 1926, at Quincy, Adams County, Illinois.  His obituary reported he was born near Plymouth in Hancock County, although on the Selective Service form Harley stated he had been born at Colchester, McDonough County.

Harley and Bessie's daughter:

Harley Dunham and Milo Currens, his brother-in-law, were riding in Quincy in a Chevrolet sedan driven and owned by the latter, when the machine crashed into a C. B. & Q. box car in front of the loading platform of the Quincy Foundry company, on Front and Jefferson Streets. The men were not discovered for ten minutes after the accident, as both were unconscious. Groans were heard by employes [sic] of the foundry and the inured [sic] men were carried into the office and medical aid summoned.

The auto is a complete wreck, all that could be recognized of it was the rear wheels.

Dunham's skull was fractured, his chest badly crushed, right hip broken, and he had numerous cuts and bruises on his face and body.  He was found lying on the right side of the car on the pavement, face downward.  Dunham was hurled out through the twisted car door and hit the pavement.  The steering shaft was bent upward in a hook formation and the wheel resting on Curren's chest. Dunham formerly lived in this community, but later moved to 1027 Jersey St., Quincy, Illinois. Dunham leaves his widow, Mrs. Bessie Dunham, his daughter, Bertha Jean aged 5, his mother, Mrs. Ruth Conboy of Plymouth, and sister, Mrs. Ray Bell of Bushnell.  He was born near Plymouth and spent most of his life in that vicinity, later moving to Quincy, and employed at Blacksmith shop.  He was an expert mechanic and a member of the Modern Woodman [sic] of America.
