Generally the estate contained quite big terrain from Chełsty to Różan. After they became also owner of a part of a village Mroczki-Kawki Many Gosiewskis still live in Chełsty and  the surrounding area. Two of the most representative members of the family were Aleksander Korwin Gosiewski, Palatine-Governor of Smolensk, Speaker of the Parliament and commander of the Polish garrison of the Moscow Kremlin. His son Lithuanian Field Commander Wincenty Korwin Gosiewski was a supporter of a strong and centralized royal power, limiting Liberum veto and a variation about how the King should be elect call Vivente rege.
