Start by calling people by the name they're best known by, and optionally add others. So Mother Theresa gets listed as that ("Saint Theresa" needs to be a disambiguation anyway), and the article should note her birth name as well as the fact that she was [beatified] by the Roman Catholic church in 2003 (other churches also have saints, but not the same list-- so we need to be specific). Ringo Starr isn't a redirect to Richard Starkey, and Gerald Ford is listed as that, not primarily as "President Ford" or by his birth name.
Looks like a common sense approach like Vicki (a professional Proofreader) suggests, is better than creating more rules.
