The House of Sanguszko is a Polish and Lithuanian noble and aristocratic family of Lithuanian and Ruthenian origin, connected to the Gediminid dynasty. Like other princely houses of Polish–Lithuanian Commonwealth, its origins are considered murky. Present historical opinion holds in favour of their descent from Algirdas' grandson Alexander, lord of Kovel and Liuboml, whose name can be shortened to Sangush. The family supposedly descends from two lines, associated with two of his sons, Alexander and Michael.
