Surname Overview
Surname Status and Pronunciation
The page lists “闺(閨)” as a surname entry and gives the pronunciation guī. However, the same source explicitly concludes that this entry is certainly an error for the surname “闰(閏)”; therefore, it does not reliably confirm 闺 as an actual surname.

Origins
Reported Origin and Evidentiary Limit
The page quotes 姓氏寻源 as saying that the relevant surname descended from kings and arose because “the king lived within the gate.” Yet the page’s own textual analysis assigns this origin to the surname 闰, not 闺, so it cannot be treated as the origin of 闺.
