History
The family traces its origins to the Łaźniński family. In the 15th century, Tomasz Łaźniński bought an estate in Stary (Old) Zamość. His sons Florian (died 1510) and Maciej assumed the name Zamoyski, and the family began to rise in prominence. Florian’s grandson Stanisław was the castellan of Chełm, and his son, Jan Zamoyski, arguably the most famous member of the family, became a chancellor, hetman, and founded the Zamoyski's Ordynat - a large estate that was a major source of the family's wealth. He was the 1st Ordynat of the Zamoyski Family Fee Tail. His son, Tomasz Zamoyski, the 2nd Ordynat, was also a chancellor in Poland. Many of their descendants held important positions within the Polish–Lithuanian Commonwealth, often that of a voivode.
