I appreciate the reply but I believe the "CH" is gutteral (produced deep in the throat) and not the crisp K in German. It may also be transliterated as an "X" or "H" in English such as in "hutzpah" or "chaim" which is from low german or yiddish. I imagine Chelor could be the same name as Hellor or Heller. I would think Kaylor or Keylor would be deriviatives of Koehler or some similar name. However, I will explore this.
