It is not known for certain whether the name Julian was adopted once she became a recluse: the authors Liz McAvoy and Barry Windeatt have both commented on the lack of historical evidence that the true names of anchoresses were ever changed to match the patron saint of the church they belonged to, pointing out that "Julian" was a common girl's name during the Middle Ages, and McAvoy notes that Julian is the old form of the modern name "Gillian".
