We visited Glendinning just a month ago. There's very little there: a small cairn as a Telford birthplace monument, Glendinning Farm itself, one house which is all that's left of the mining village of Jamestown; and that's about it. It is also at the very end of the road - except for a forestry track going further up the valley. There's a scatter of other houses /farms down the valley; and they'd have had to walk three or four miles down the valley to the church, where his dad is buried. But it is beautiful, as well as lonely. I can imagine Telford and others being keen to get away, or being delighted to stay!
I've attached pictures of the valley; and of his dad's grave in the Westerkirk burial ground.
Best wishes! David
