[Mediawiki-l] Category page name sort logic.

[Michael Daly]

I noticed this on Wikipedia and assume it's a generic MW thing.

In a category of persons, I see the list of articles where some persons 
are listed under the first letter of their first name and others by 
their last name.  E.g.:

A
John Adams

B
Barney Rubble

I looked at the [[category:..]] statements in the articles and couldn't 
see anything that could explain it.  How does it decide whether to use 
first or last name and how does it know it's a name of a person and not 
just a two-word article name?
