Not one of the surnames mentioned, but the woman who previously lived in my house was Norwegian and my 90 year old mother in law tells me that the lady's parents came from Norway to establish a nail factory in Portishead. My m in law says the lady's maiden name was Johansen. Her Christian name was Dogny (hope spelling right). She had a large family, mostly all gone, but I know of one still alive. If subject still ongoing, I could try to find out more from her.
