Why the "real name" question matters

Search interest in a celebrity's "real name" usually means one of three things: a shortened everyday form (Tom for Thomas, Dave for David), a middle name used as a stage handle (Drake-style), or a true legal/professional change after immigration or branding. This sprint page states which case applies, cites library or encyclopedia authorities where possible, and avoids gossip.
