Excellent explanation, PhD Historian, thank you. So it seems that even at the time the opinion was split between "can" can "cannot" for the monarch to issue succession. Had you have said that undoubtedly Edward had the right, I would then consider all monarchs since that time to be illegitimate, but since the "not" faction won we can only go with what history has left us. It’s a shame, really, I wonder what kind of Queen Jane would have been…and we know what kind Mary was.
