Meaning & origin

Thomasene is a rare feminine elaboration of Thomas that first appeared in U.S. records in 1927. Its peak year was 1942, yet even then it never ranked in the top 1,000 names. The name has remained exceptionally scarce, with no recorded births in most years. The 1-in-N rate is effectively incalculable due to this rarity. Thomasene follows the pattern of other -ene suffixed names like Geraldine and Josephine, which were more popular during the same era. Its trajectory has been stable but with near-zero usage. The name is primarily associated with the 1940s, though it never broke into mainstream popularity. Thomasene is a distinct choice for parents seeking a vintage, feminine derivative of Thomas, but it has no significant presence in any U.S. state or cultural group.

Thomasene is a feminine elaboration of the name Thomas, formed by adding the feminine suffix -ene. Thomas itself derives from the Aramaic name Te'oma, meaning 'twin'. The name Thomasene emerged in the early 20th century as part of a trend of creating feminine variants of traditionally masculine names, though it never achieved widespread popularity.
