Hiya,
Probably not a connection but my paternal grandfather, William John Corbett, killed his pregnant wife, Ethel Louisa Jones, by cutting her throat in March 1931. This occurred in Glamorgan Wales. He was hanged at Cardiff prison in August 1931.
Looks like the area wasn't the same for you?
I'm certain I must have some living relatives on my father's side as they had quite big families.
I found the British Library most helpful. I sent them the sketchy details I had and they came up with 8 newspaper articles of the time. One of them was an obituary for my grandmother which included loads of relatives' names.
All the best!
Angela
