Regina Nurse Mystery

Hello again. I thought I'd start my August posts with a mystery. I have recently acquired a photograph of a Canadian nursing sister. It was taken in Regina at the Rossie studio. There is no evidence of who the nurse is. The only clue is that her photograph was included with a Christmas card from an Olive Peacock to a Frank Bellamy. However, no nurse by the name of Olive Peacock appears to have enlisted in the CAMC. Any help in identifying this nurse would be gratefully received.
