Sc lang + Sc struther

‘Long marsh’. Sc struther or strother occurs comparatively infrequently north of the Forth-Clyde line (see DOST under strother). When it is first recorded it is part-translated into Latin, which may mean that struther is functioning here as a common noun rather than a place-name.

Langstruther # first appears among the lands of Cumberland # KCQ (q.v.), poor lands attached to St Mary’s Chapel at Rires KCQ.
