Isebell is of French origin, derived from the Occitan name Izabel or Isabeau. It means 'devoted to God'. The name is a variant spelling of Isabel and Isabella, which were popular during medieval times due to Queen Isabel of France's influence.
"Isebell is quite rare; only five girls were named Isebell each year between 1927 and 2018, with a total of five births over that period."
