I can't find any good articles discussing the reasons for the differences in the spelling of Monk's first name/stage name. His wiki page says his birth name is "Thelious Monk Jr."
Surely someone has written about this, right?
EDIT: I forgot I was using a Firefox extension that swaps “Elon” to “Elmo” and I guess it was doing it within words too. LOL
I feel like I'm having a seizure reading this. Please fix the spelling of what you are trying to ask.
Thelonious Sphere Monk was born on October 10, 1917, in Rocky Mount, North Carolina, the son of Thelonious (or Thelious) and Barbara Monk. His sister, Marion, had been born two years earlier. His birth certificate spelled his first name as "Thelious" and did not list his middle name, taken from his maternal grandfather, Sphere Batts.
After the correction, I have no answer for you. "Thelmoious" returns zero web search results. No one here has ever heard this name or seen this spelling before you posted this question. I assumed it was a typo.
I was using a Firefox extension that was changing “Elon” to “Elmo”… I didn’t put a space before and after “Elon” in the prompt, so it was changing it everywhere. Even within words.
