Tandy is an uncommon given name with unknown origins. Some believe it may be derived from the Irish surname O'Tandy meaning "freckles," but this connection is not widely accepted. Despite its mysterious roots, Tandy has gained popularity through literature and popular culture, notably used as Phoebe Caulfield's nickname in J.D. Salinger's "Catcher in the Rye." Today, it remains a rare yet distinctive choice for parents seeking an unusual name for their child.
