The House of Bordzià Âowski (, , ), also known as Harbuz-Bordzià Âowski, was a noble family of the Grand Duchy of Lithuania and later the Russian Empire. The family is associated with the Biaà Âynia coat of arms.
There are several theories regarding the origins of the family name and lineage.
Linguistic studies on Belarusian anthroponymy suggest that the root of the surname, Bardzila, may be derived from the name of the 13th-century Lithuanian duke (mentioned in the Hypatian Codex as a brother of Traidenis).
According to the family's own tradition and heraldic legends, the Bordzià Âowski line (specifically the Harbuz branch) originated from Greater Poland (Duchy of Masovia) from a warrior named Harbuz, who is mentioned in records as early as 1332 during the reign of King Ladislaus the Short. Some sources also mention the family's establishment in Mazovia around 1480.
Documentary evidence firmly places the family in the Mstsislaw and Vitebsk Voivodeships (specifically Krychaw starostwo) of the Grand Duchy of Lithuania by the early 16th century.
The first documented representative, Ivashka, owned a number of estates in the Krychaw starostwo based on privileges from King Sigismund I the Old (1523) and Prince Vasily Solomeretsky. Some narratives suggest he may have served in the army under Vasili III of Russia or the Polish Crown, but it is confirmed that for his military service he was granted the estate in the village of , which became the nest of the family.
In the 17th century, the family expanded significantly, and its members held positions in the local administration and served in the military. For example, Benedykt Bordzià Âowski was a major in a pancerni banner under the command of the Voivode of Vilnius Michaà  Kazimierz Pac (1680).
The Bordzià Âowskis were recognized as nobility by the decree of the Minsk Noble Deputy Assembly on 6 August 1802 and were entered into the 1st part of the Noble Genealogy Book.
The family's initial possessions were located in the Krychaw starostwo. The progenitor Ivashka owned the estates of Baà ÂaÃÂynskaje, Kaà Âyà ¡eà Âskaje (possibly the folwark Staroje Siaà Âo in the Mogilev district), Taà ÂpyÃÂanskaje (probably the folwark Papoà Âka), and Dalhaà ¡eà Âskaje, as well as the estates of Bardzily, Makryda, and Halna Slabada. The privilege for these lands from Sigismund I is dated 9 May 1523.
In the 17th and 18th centuries, the estates were fragmented among numerous descendants. In the 19th century, family members owned or lived in estates in the Orsha Uyezd, Rechytsa Uyezd, Grodno Uyezd, Lida Uyezd, and Borisov Uyezd of the Russian Empire.
