Girl name · 173 babies recorded · 1974–2025

Tamsin: 173 babies born in Scotland since 1974, given to girls, peaking at 11 births in 1992.

Tamsin is the English and Scottish contracted form of Thomasina, the feminine version of Thomas, which ultimately comes from the Aramaic *t’om’a* meaning “twin.” Perhaps its most famous bearer is the acclaimed British actress Tamsin Greig, beloved for her roles in *Green Wing* and *Friday Night Dinner*. While the name itself doesn’t anchor any specific place, its root links it to the biblical Saint Thomas, after whom numerous places like St. Thomas in the Caribbean are named. A charming alternative spelling is Tamsyn, which you’ll occasionally see in Cornwall, while the affectionate, time-worn nickname Tamsie gives it a distinctly Scottish homeliness.
