Meaning & origin

Nillie is a rare diminutive-style name that has all but disappeared from American birth records. It first appeared in 1913 and saw its peak usage in 1927, a year when many similar nickname names flourished. The name has not ranked in the top 1000 since the mid-20th century, and its trajectory remains extremely stable at near-zero usage. Nillie was recorded in no top states in any year, underscoring its sporadic, low-volume occurrence. As a variant of Nellie or a short form of Cornelia, Nillie fits the vintage nickname style that occasionally sees revival, but as of the latest data it remains a relic of an earlier naming fashion.

Nillie is a variant or diminutive of Nelly, itself a pet form of Eleanor or Helen, but it may also be a short form of Cornelia. The name saw modest use in the early 20th century, particularly in the 1920s, but has since become rare. Its exact derivation remains uncertain, as it may have emerged independently as a nickname.
