Something different to talk about. I have wondered for some time if it is really the case that we have not addressed the issue of "alias" names, where the point may simply be alternate spellings. This is not particularly important for contemporary names that are already Romanised. It is certainly matters if you go back several centuries, given that spelling was not standard.
As far as I can see [[Wikipedia:Manual of Style (biographies)]] doesn't cover this ground, while dealing with numerous points in the same general area of naming. My instinct is that multiple possible spellings, for example surname variants, should go into a footnote or perhaps be boxed up, as a way of keeping them from distracting the casual reader. They are certainly of interest to specialists and scholars, and have a role to play in making search work.
