Question: Who had only one brother and was a british executioner for 23 years?
Sentence (from "Arthur B. English"): He probably used the pseudonym of Arthur Ellis after the famous English executioner, John Ellis: there is no truth in the story that John Ellis was his uncle, as John Ellis only had one brother, James Preston who was born in 1887, and therefore would have been only 25 when Arthur Ellis started his career.
Relevant evidence: Yes
