For a time I worked for J.C. Penney’s, taking catalog orders. In New England, many of the names of cities and towns were from the local tribes, and I often had to deal with things on the order of ‘Chaubunagungamaugg’ or ‘Ouacachapassit’. I think that those long-ago natives must have had a perverse sense of humor.
They more than likely had the sesquipedalianism gene as dominant.
