From personal name: This is a redirect from an individual's personal name to an article titled with the subject's professional stage name, pen name, or other better known moniker.
This redirect leads to the title in accordance with the naming conventions for common names; it may help writing and aid searches. It is not necessary to replace these redirected links with a piped link.
If this is the name of a living person, then one or more reliable sources must be included in the target article that will support the existence of this personal name, or else this redirect's talk page must be created and the reference(s) added there. This is in accord with Wikipedia's biography of living persons (BLP) policy, which applies to all Wikipedia pages, to include redirects.
Use this rcat only on redirects that are in Wikipedia's main-article namespace, and only when the personal name differs from the subject's name when born. If the redirect title is the subject's birth name, use {{R from birth name}} instead.

From an alternative name: This is a redirect from a title that is another name such as a pseudonym, a nickname, or a synonym of the target, or of a name associated with the target.
This redirect leads to the title in accordance with the naming conventions for common names to aid searches and writing. It is not necessary to replace these redirected links with a piped link.
If this redirect is an incorrect name for the target, then use {{R from incorrect name}} instead.
