Meaning & origin

Sissy first appeared in U.S. birth records in 1944, but it has never been a common name. Its peak popularity occurred in 1981, when it reached its highest number of births. Since then, usage has declined and stabilized at very low levels, with fewer than 5 annual births in recent years. The name's trajectory has been stable, indicating a small but consistent presence. Sissy is most often a nickname for Cecilia or simply a familiar term for a sister, though some parents have chosen it as a standalone given name. Because it is rare, the name stands out and carries an informal, affectionate tone. Top states for Sissy in its peak decade (1980s) were not recorded due to its rarity.

Sissy originated as a diminutive or pet form of Cecilia (or sometimes other names beginning with 'Sis-'), as well as a colloquial term for a sister. It gained limited use as an independent given name in the United States, particularly in the early 20th century. The name saw its peak popularity in 1981, though it has remained a rare choice.
