ROBERT CLIFTON SINGLETON, B.C

I have been looking for the family of Robert Clifton Singleton. Robert was born on 4th October 1887 in Sunderland, Co. Durham, England & brought up in the Orphanage. He left England & went to San Jose Mines, Texas with Frederick Dunn Alderson, where they were robbed. They then travelled to British Columbia to work in a mine in Hosmer. Robert married a girl called Eleanor but I do not know her maiden name. Robert & Eleanor were living in Merritt, B.C. when he joined the Canadian Engineers as a sapper he was sent to England in 1916. After his training he was posted tp Flanders & was killied 4 weeks later on the 7th June 1916. Eleanor moved to Calgary. Can anyone help me?
