Dominik Kossakowski (; 1711âÂÂ1743) was a Polish-Lithuanian nobleman, a member of the noble Kossakowski family of the à Âlepowron coat of arms, and the founder of Jonava.
He was born into the noble Kossakowski family of the à Âlepowron coat of arms, using the Korwin cognomen. His father was Jan Mikoà Âaj Kossakowski, a stolnik of Kaunas, and his mother was Anna, née Skorulska. He was their only son and, as such, the sole heir to the estate of the Lithuanian branch of the Kossakowski family.
Kossakowski began his military career by becoming a lieutenant in the Petyhorcy cavalry regiment. Politically, he aligned himself with the Sapieha faction, which supported the election of Stanisà Âaw Leszczyà Âski. After the coronation of Augustus III, he left the country and settled in Königsberg. Upon his return in 1735, he was appointed land judge of Kaunas, and two years later, he became the stolnik of Samogitia. He died young, at the age of 32, in Jonava in 1743, and was buried in Kaunas.
He was regarded as a good and progressive landowner, commissioning numerous drainage works that improved and expanded the land he owned. Between his own estates and those of his wife's family, he founded a town, which he named Janów in honor of his father (today Jonava, in Lithuania).
In 1732, he married Marianna Zabieà Âà Âo, the daughter of Michaà  Zabieà Âà Âo, the land judge of Kaunas, and Anna, née Biaà Âozor. Together, they had four sons: , , Józef Kazimierz and Szymon Juda Marcin, between whom the estate was divided. His only daughter, Anna, married Karol Czarniecki, the son of the castellan of Bracà Âaw, Jan Antoni.
