Landsberg family

The earliest mention of the family dates back to the 11th century, they trace their roots to a ministerialis who lived in 1055 at the Werden Abbey.

Their last name comes the Landsberg Castle [de] in the Duchy of Berg, which was still in the hands of the German representatives of the family in the 20th century.

Only Tomasz, great-grandson of Rafał Landsberg, who married Marcjanella Kierbedź, came to greater prominence.

His son Stanisław married Salomea Szemiot, through which he came into possession of the large estate of Šiaulėnai.

He came from the impoverished part of the family; his father was Wincenty Ananiasz, son of Kazimierz Ignacy and grandson of mentioned earlier Rafał Landsberg.
