Idea for sleuthing it out, not policy-making, although I think it's a very good point to resolve.
Idea: Check on the descendants and see if they have resolved the spelling issue. You can still use just one of the spellings you already have, maybe on the profile that was created first, and add a string of aka's to it. I've seen that with the surname, which I find distracting, but certainly covered first thing in the Bio would be useful to future searchers.
Just an idea.
