This doesn't change the fact that the person that committed one of the worst genocides in history was given this name. As France was an allied country that also wouldn't work.
OK, here's the problem:Any form of Adalwolf, ie Adolf, Adolph, and this name, will be associated with the National Socialist Party leader Adolf Hitler.As I have said in the Adolf comment section, any form of the name should be pronounced differently or be abandoned for a permanent nickname. I knew an Adolphe once (who pronounced it ayDOHLF in formal company and bore the nickname Addy among the students). But its spelling is the clincher for the immature igronamii of the bunch.
France was so decimated by the Third Reich and its genocidal war on their soil that no self-respecting Frenchman would find Adolphe to be an acceptable name to give a child. Maybe that will change in a few hundred years, but not today.
