Tittle = Tickle

In Black Country dialect the word tickle is pronounced "tittle".
For readers unfamiliar with this part of the world: the Black Country is the large industrial (or perhaps now post-industrial) conurbation to the west of Birmingham, in central England.
In an earlier comment Edgar Gregor told us...
In the Frodsham area of Cheshire the name is sometimes spelled "Tickle" in the parish registers of the 18th and 19th centuries.
