I would think an encyclopedia is there to give 'facts'. Her name is not capitalised, so we should give that fact. I can understand the technical limitations, but the fact that it is English rules to capitilise seems, in my oppinion at least, outweight by the 'legal'(correct way) of spelling the name. For brands or nouns that don't have a capital, it is different, unless they actually state that it should be spelled one way or the other. The day Adidas decides that it can only be 'adidas', then that would be more important then the general rule. Rules have exceptions and this seems to be one. How does Wikipedia spell noble names (de Frenchnamehere,van Dutchnamehere...)?
