Actually "Jehan" is the medieval masculine form of "Jean" pronounced [zhã] and would have being pronounced the same since "h" is mute in French. It would be the equivalent of the English "John" .
However, the English "Joan" which is "Jeanne" in nowadays' French is pronounced [zhan'] and was originally spelled "Jehanne"; same pronounciation as the modern form.
