That was once the case, Bruce, but no longer ~~ the wiki entry on Cockney is informative on this matter. The term Bow Bells was always in dispute anyhow: some thought it meant the Church of St Mary le Bow in the City of London, which had a famous peal of bells, others Bow Church in the suburb of Bow further east along the Whitechapel & Mile End Roads {the A11}.

Anyhow, to return to OP, hands up who else had never realised that Dinah's father Villikins was actually called Wikins? & who has any
examples of comparable misunderstandings?, which was what I was after.

Did you know, BTW, that Dinah, the name of Alice's cat in Wonderland & Through the Looking Glass, was actually the name of one of the cats owned by the Liddell family - Alice Liddell, the daughter of Dr Liddell the Dean of Christ Church Oxford where Dodgson {Carroll} was also a Fellow, being the original Alice to whom he told the stories in the first place; and they actually had another cat called Villikins? One of those time perspectives which blow my mind is that she & I were alive at the same time: I was born in 1932, Alice Liddell died in 1933.
