Meaning: Its source is Treasaigh, an Irish Gaelic name meaning "Warlike."

This name is sometimes spelled TraciLyn or Traci Lyn.

Narrative: There is a tradition that Tracy originated as a nickname for Theresa. Another possible derivation is from a Norman French place name, itself based on a Gallic Latin personal name, Thrax or Thracius, whose meaning has been lost.

Two great actresses boosted awareness of this name in the middle of the 20th century. The character Tracy Lord was played by Katherine Hepburn in the 1940 film version of Phillip Barry's Broadway hit The Philadelphia Story. Sixteen years later, Grace Kelly portrayed the same character in a remake titled High Society.

The Tracy these two screen beauties portrayed is an idle heiress, at once smart, funny and vulnerable.
