That is very interesting because I notice a close affinity between Edinburgh and Holland. It is often expressed through architecture. Edinburgh and Glasgow have a great number of purpose built flats (tenaments) which are much more common in Northern Europe than in English Cities. The step gables that can be seen on Dutch roofs are called "crow steps" here (and crows do seem to like to climb them). Culross in Fife on the Forth of Forth dates back to 1597 and the Dutch influence on the architecture, probably because of visiting Dutch traders arriving by boat is very obvious. So the word could well have arrived by boat and was adopted along with the architecture. I'm sure there may be a more "academic" explanation. I wonder if there are other Dutch words which were adopted by Scotland but not England.
