I spotted this in the newspaper.
Newcastle Evening Chronicle - Saturday 09 January 1943
"Newburn Urban District Council War Time Nursery, Applications are invited for the appointment of four Probationers at the War-time Nursery Central Recreation Ground, Newburn from Girls between the ages of 16 to 18 and interested in the care of young children. Salary £40 per annum. Applications stating age, qualifications and experience endorsed 'Probationer' to reach me not later than Jan 19 1943. Thomas Shaw, Clerk to the Council, Council Offices, Newburn, Northumberland."
So if I've understood that correctly, that must mean there was at least one nursery in Newburn connected to the war, by January 1943 at least. I can imagine they might have had cooks?
Weirdly, I can't find any other reference to the 'central recreation ground' so I'm not sure where that was supposed to be within Newburn.
