Pityaka,
I am surprised that you do not instantly remember Morgan's chippie in Newsham. It had the most prominent site in Newsham. It was directly in front of the railway crossing when looking towards Blyth. Now there is a roundabout where it stood.
I think that there might have been another chippie in Newsham in my very early days. I only have one very early, vague memory of it. Do you remember the wooden hut where Jimmy White had his barber's shop, before he moved on to Plessey Road? It was next to the railway line between the crossing and The Black Diamond. Well, I think there was a chippie, a black hut, there, next to Jimmy White's. It must have closed around 1950, or soon after.
I was reminded by a friend, that there was another chippie down Blyth near Ridley park, perhaps on Briarwood Road. I have a very vague memory of going there once, probably around 1960, but it's all very vague.
