The name Darcy ranked 802nd in popularity for females of all ages in a sample of the 1990 US Census.
Though this name has fluctuated in use, it has been quietly present throughout the last century.
It originated as a surname for some of the Norman barons who invaded Ireland after the conquest of England in 1066. Spelled d'Arcy, it identified them as hailing from a place in Northern France called Arcy.
This name may have converged over time with a surname derived from the Gaelic O Dorchaidhe, meaning ''dark man.''
