Weird, I am looking at OS OpenMap Local (October 2022) in JOSM and it just says Glenrath Heights here, nothing else. OS OpenData StreetView (April 2016) has Middle Hill.

The old NLS maps in JOSM agree with you, boo_radley.

Wikipedia calls Glenrath Heights a hill and a summit, this is where I initially noticed it, because we don’t have anything called Glenrath Heights.

So should we add Glenrath Heights as a locality roughly where the NLS maps show it (further south)?
