Tamasen is Cornish in Origin.

Tamasen blends English Cornish diminutive lines of Thomasina with a -sen ending familiar from Germanic patronymics. The root is Thomas (Aramaic Ta’oma’), meaning “twin.” In medieval England the feminine Thomasina/Thomasin circulated; in Cornwall it contracted to Tamsin/Tamsyn. Tamasin developed as a literary and modern spelling, and Tamsen appears both as a Low German surname and a given-name variant; Tamasen aligns with these influences.

Use is rare but recognizable in the UK, US, and Australia since the late 20th century, echoing the revival of Thomasin(e)/Tamsin forms. Bearers of the close variant Tamsen include Tamsen Donner of the 19th-century Donner Party, which helps anchor the name’s visibility. Common variants and cognates: Tamasin, Tamsin, Tamsyn, Tamzin, Tamsen, Thomasin, Thomasina; related nicknames include Tam and Tammy. Core meaning across all forms remains “twin.”
