Cafflein is in Origin.

Cafflein is a contemporary, rare given name in English, likely coined by blending familiar Irish-influenced -leen endings (as in Caitlín/Kathleen) with the Caff- element seen in Irish surnames like Caffrey or Caffey. The spelling also echoes the German diminutive suffix -lein, adding an affectionate, light touch, though the name is not German in origin. Usage is modern and uncommon, emerging in creative naming circles in the late 20th and early 21st centuries, typically for girls because of the -leen sound.

With no single established etymology, Cafflein’s meaning is interpretive. The -leen/-lín pattern in Irish names functions as a diminutive, suggesting “little” or “dear,” while association with Caffrey (ultimately from Geoffrey) can evoke the idea of “peace” through the frid ‘peace’ element. Variant spellings include Caffleen, Cafflin, Caffline, and Cafflene; related names include Kathleen, Caitlin, and Eileen.
