WikkedWillisSaga is based on the fictive life of a real cat that was born in the shop at Lochboisdale Pier. He found a home with a nearby crofter, Mairi Anndra, who shared her house with American folklorist and song collector Margaret Fay Shaw. When Margaret moved to Barra to marry John Lorne Campbell, Mairi insisted she take with her this remarkable cat. Willi stayed with her when the couple later made their home in Canna.
