"is 'Cather' a local/poetic name for the Calder which flows through Lochwinnoch?"

Interesting idea, Steve.

I probably can guess your attitude to Crawfurd's material, but if you've anything specific to add I be happy to hear it.

I have seen the Chambers 'Tempted Leddie' with the cantefable bookends. I thought that and Crawfurd were the only examples, hence my interest in any corroboration from Kinloch.
