Here is the extract from the place name research undertaken on the Cateran Trail by the Cateran’s Common Wealth project:

Glour-o’er-him Wood 1901 OS 6 inch 2nd edn PER & CLA LII.SE

This is a humourous name attached to a wood. It is not known what the circumstances of its naming are. However, it belongs to a category of place-names called verbal place-names and perhaps it is best to let Simon Taylor explain what they are: ‘[this category] comprises names formed as verbal constructions. This class of names belongs to a wider category of humorous and ironic names which seems to have flourished in the eighteenth and early nineteenth century, and were affectionately ridiculed by authors such as Sir Walter Scott, which partly contributed to their spread, but also possibly to their ultimate demise.
The wider category to which they belong, that of humorous or ironic names, generally consists of names which refer in some way or other to poor land and difficult living and working conditions. As names applied to late, marginal settlement, it is scarcely surprising that they make reference to hardship: what is noteworthy is that they do it with humour, even if that humour is sometimes expressed, as it were, through gritted teeth’ (Taylor 2008a; see also PNF 5, 214-15).
