In 1992, members of the Lewis Carroll Society attributed it to a gargoyle found on a pillar in St Nicolas's Church, Cranleigh, where Carroll used to travel frequently when he lived in Guildford (though this is doubtful, as he moved to Guildford some three years after Alice's Adventures in Wonderland had been published) and a carving in a church in the village of Croft-on-Tees, in the north east of England, where his father had been rector. [16]There are numerous theories about the origin of the phrase "grinning like a Cheshire Cat" in English history. A possible origin of the phrase is one favoured by the people of Cheshire, a county in England which boasts numerous dairy farms; hence the cats grin because of the abundance of milk and cream.

Carroll wrote in his memoirs that he "saw a Cheshire cat with a gigantic smile at Brimstage carved into the wall". This refers to a roughly-cut corbel in Brimstage Hall, Wirral (previously in Cheshire) which resembles a smiling cat. This is another possible inspiration for the character.

The following quotes are often mistakenly attributed to the original Alice in Wonderland books. However, they are in fact from other people, songs, or movies based on the books.

At one point, the cat disappears gradually until nothing is left but its grin, prompting Alice to remark that she has often seen a cat without a grin but never a grin without a cat.
