Here are two photos from north Northumberland schools, both dating from around 1950.
The bottom picture, of the Duchess’s School, was provided by Michael Clements and features his grandmother June Lane (née Holland) on the back row, third from the right. The headmistress of the school at the time was Miss LG Lloyd, but Mr Clements doesn’t know any of the others pictured.
The top picture, provided by Marjorie Robinson, is of Hepple School. Most of those featured are known, apart from the girl fourth from the left in the second row from the back.
