Brian again!

While I remember, about the word Cather you were asking about above and Steve suggested might be a local name for the Calder.

Lyle's notes to the song in Vol1 say:

"..and evidently Crawfurd was responsible for substituting the River Calder (which runs through Lochwinnoch parish) under its old name of 'Cather', which occurs eg on the cover of a letter dated 1740 that was in Crawfurd's posession and is now in Paisley Central Library"
