I was not actually doing any research, but after my grandmother died, at the age of 97, we discovered that she had been married before my Grandad, losing her first husband during the second world war. We also discovered that my grandad had been married before, and divorced. My mother, their only daughter, did not even know any of this, even though she was very close to her parents. My grandmother, who I spent a lot of time with, never ever spoke about her first husband, not even on the odd occasion that I would question her about the war and what life was like. Her two sisters, still living, did know but had never mentioned it either. My mother only found out from a photo and documents when she cleared out her flat after she died.
