Morpeth Herald 10/09/1915 carries a brief obituary:
Mr and Mrs Trayner, of 7 Cummings Buildings, Blyth, received official intimation this morning that their son, Corporal John James Trayner, of the East Yorkshire Regiment, had been killed in action at the Dardanelles. Mr and Mrs Trayner first heard of his death last week, but on Saturday morning they received a telegram to the effect that no casualty was reported of Corporal Trayner. This morning’s intimation, however, has put the matter beyond all doubt. He was only 23 years of age, was married, and worked as a coal hewer at Crofton Pit prior to the outbreak of war.
He is remembered as Traynor, J.J. at Blyth on B42.24 and at Cowpen & Crofton on C58.01
