Meaning & origin

Thomasina is a rare feminine derivative of Thomas, first recorded in the United States in 1904. Its peak usage occurred in 1975, after which its popularity has been steadily falling since 1985. The name has never broken into the national top 1,000, and it maintains a 1-in-N ratio that is too small to estimate from available data. Its top states have never reached a significant threshold, and similar names include other traditional feminines like Georgina and Louisa. Thomasina offers a distinctive, classic feel, but its rarity means it stands apart from more common choices.

Thomasina is the Latinized feminine form of Thomas, derived from the Aramaic te'oma (twin). The name entered English usage in the Middle Ages, but remained rare until the 19th and 20th centuries. It was given sporadically in the United States, with occasional use in British and American families.
