Jimmy C. ---In my home village in Ayrshire, there is a small hill named the "Shillin Hill". The origin of the name lies with the function, carried out over possibly hundreds of years, of threshing corn ["corn" is the name applied to oats in most of Scotland]. The remains of the old mill are still to be seen at the site---and its neglect by local officials gives me cause for some rage, incidentally. "Shellin" or "shillin" was the word describing the winnowing of the chaff from the kernel. Maybe there is a connection there to the "sheiling"?
