Ton-That


Ton-That and Tôn Nữ is a two-character Vietnamese compound surname, originating from the Nguyễn dynasty. It is the surname for members of the imperial family that were not direct first-born descendants of the Emperor, and therefore considered collateral relatives of the Nguyễn dynasty.
This surname was originally Tông Thất, which is derived from a Sino-Vietnamese word, meaning "clan members" or "royal family members". The surname was changed to Tôn Thất after Thiệu Trị became the emperor due to naming taboo.
