She Might Be My Grandmother

I found this photo in a pile of old family photos and I don't know who she is. She might be my grandmother, my father's mother. but I just am not sure. She died before I was born and there were very few photos of her. And I don't have a sense of her.

She was married when she was 19 in 1916. She had four sons in ten years and maybe two stillbirths. She died in 1947 and we are not sure what caused her death. I always thought is was heart condition. But my sister thought it was cancer. And all of my father's generation is gone and so is the truth of the matter.
