Oh, and creel - when I was little we called the big pannier baskets slung either side of a donkey to collect seaweed or turf creels. These things.

However, creels could also be any kind of large basket. Personally I'd plump for peat (in other words, turf for burning) in the creel, meaning she always had a warm fire; the hearth being the centre of the Gaelic home.

Rowan is indeed mountain ash, and grows happily in the acid soil of the Atlantic coast of Ireland, and I'm sure of Scotland too.

A shieling is originally, I think, a bothy thrown up to store feed for animals while booleying; by extension it's a little home. The lover in My Lagan Love likes to steal into his mot's "shieling lorn".
