History & Origin

Trinia is a coined name resting between Trina and Trinity. Trina is a short form of Katrina or Katherine, from a Greek word for 'pure', while Trinity comes from the Latin trinitas, 'three'. Trinia borrows the shape of both without settling firmly on either, in the free-coining spirit of its era.

Trinia was a rarity throughout, peaking around 1970 at about thirty girls a year and fading by the late 1980s. It belongs to the mid-century wave of invented, euphonious girls' names; a Trinia today would be in her fifties, and the name has stayed obscure.

Did you know? Trinia sits a half-step from both Trina and Trinity, so depending on which neighbor you hear, it whispers either 'pure' (through Katherine) or 'three' (through Trinity).
