Meaning and history
Tracy comes from an English surname based on a Norman French place name meaning "domain belonging to Thracius." Charles Dickens used it for a man in The Pickwick Papers (1837), while Tracy Lord in the film The Philadelphia Story (1940) popularized it as a feminine name; it is also sometimes a diminutive of Theresa.
Tracy moved from #820 to #951 for girls between 2003 and 2004. Its highest annual birth count came in 1970, with 18,464 births.
