Wainstalls Waifs

We walked seven miles, up and round the Dean Valley today. I was going to blip the gatehouse at Castle Carr, but decided on the grave of the Wainstalls Waifs, after watching the series, The Mill, recently on TV.
The grave on the blip is of orphans, brought to the upper Calder Vally from Liverpool at the end of the 19th century. From what I've read about them, they were little more than slaves.
