Many thanks for the information you've posted, that's really interesting. If you've got any other details of the William Bowles line, I'd be really keen to see them.
Do you know what the date of the paper cutting is? I'd not got any details of William Bowles's father, so that's fantastic, as it not only gives his name but his date of birth (roughly) and the date he died.
I've attached an exert I found in a Victorian Nottingham book that describes a bit more about his time in the police force. I've also got a picture of him, which I'll dig out and post.
