Liechtenstein categories
I have reinstated the categories on the redirects, When I converted these stub articles to redirects, I intentionally left the categories in place. Princess Georgina of Liechtenstein, for example, is still a Princess and and a 2005 birth even though she no longer has an article to herself. Basic biographical details (birth, marriage, children, death) for all these people are on Princely Family of Liechtenstein, which is the target of the redirects.
