Well, of course, the existence of the word "myrrh" is where the parents got the idea that Summyrrh could be a respelling of
Summer. This is an example of where it's wrong to automatically call respellings one doesn't like "illiterate". The problem these parents had is that they were a little
too literate in the sense of knowing too many different ways that one can spell the sound "mer" in English. :)
