Memorabilia of Herbert Grant, Canadian Expeditionary Force, 5th Field Ambulance Force, C Section

My great granduncle, Herbert Grant, was born in Charlemont Mall, Dublin, Ireland in 1895. He went to Canada in 1911. He seems to have gone to Michigan and then back to Canada where he joined the Canadian Expeditionary Force. He was in the 5th Field Ambulance Force, "C" Section. He fought and died at the Somme. No body was recovered but his hat was found. He was a stretcher bearer and went into the field. Five men died and the person on the stretcher survived. One of the letters is from Harold Hill to Alice Grant, Herbert's sister. We assume that Harold also died. There is a family story that Alice's fiancé died. She never married and kept all the memorabilia. There are no photographs of him.
