Hmm I think this is like the story that suggests that the native American word "Moccasin" is actually a corruption of the Scots Gaelic "mo casan)(sp?) - - "my feet".There's all sorts of cod-etymology trotted about and there always has been. Sometimes things are floated as quasi-jokes, and attain currency - cf. Mr Crapper the "inventor" of the flushing toilet.
One of my favourites is the suggestion that a district in Glasgow called Cowcaddens was named that because there were cow-byres there and the cows' lowing led to the place being called "Cow-cadence".
