According to the military history sheet for “James William Rotherham” “alias James Wm Flint”, 3/7283, he married Alice Maud Clews, spinster, Parish Church St Mary’s Sheffield. Witnesses were Frederick Jinks and Elsie Shipley.
There was an Elsie Shipley 15 in the household of Robert Walter Shipley & Eliza Agnes Shipley in 1911 along with Alice Maude Shipley 18 & 5 other children.
"When you found the Military sheets for James did you use the surname Rotherham or Flint?"
I was searching for anything about Alice Maud Clews. They indexed relatives names on the record too. A child's name was on the military sheet; and the mother Mrs Rotherham.
As a by the way, and a lesson in being wary, there are family trees on Ancestry that claim Robert Rotherham / Flint died in France in WW1!
