Names are very personal and for some very public. Shakespeare still said it with the most simplest of phrases:
A rose by any other name would smell as sweet.
That quote can be applied to so many different ideas one being the spelling of a name. A person’s name; a group; or, a place.
The Beatles made it a point of their choice of spelling. Led Zeppelin played on the spelling of their name. Would their music or their creativity be any less if they followed conventional spellings. I actually think it would. Choosing a variation of a name’s spelling to gain an artistic impetus is every creative author’s right; and, with that I will reiterate: I AM JELLYBEEN! Taste the sweetness of artistic license.
