This is very interesting, and I'm wondering at this point, why some records were kept, while others weren't.
In my case, my grandmother has no living relatives. I wish she did as I could ask them about all of this. She had a sister, who passed away many years ago (about 35 years ago). My grandmother had two children, my mother and her brother, and they have both passed away. So I'm it.
I'm going to try the Salford Archives and see if they can help. I also have no idea if she was cremated or buried. Does anyone know what the procedure was when someone passed away in a mental hospital? I also wonder about this as my Mom was told at the age of 6 that her mother had died, but she didn't really die until my Mom was 7-1/2. My Mom had no recollection of a funeral, so I also wonder if when my grandmother died, if everything was kept hush hush. My grandfather did give my grandmother's engagement ring to her sister, who subsequently gave it to my Mom, and now I have it. That and one photo is all I have.
