The article investigates the history of Ivashchenko family from the village of Letski (Pereyaslav-Khmelnytskyi district of Kiev region) in the 17th and 21st centuries. The lawful past of the Ivaschenko family reflects one of the typical life strategies of the Ukrainian peasant family of Cossack descent from Central Ukraine. The founders of the family affirmed their knighthood, having served several generations in the ranks of the Zaporozhian Army. Their descendants in the 17th and 19th centuries managed to preserve personal freedom and continued to call themselves proudly Cossacks. The tribe existed and developed successfully through tireless labor on earth and large families, which became the main guarantee of the continuation of the family. The scientific novelty of the research is that at the moment no detailed analysis of the history of the Cossack family of Ivashchenko from the village was conducted. These materials were not the subject of independent study, therefore the analysis of this problem will help to analyze the contribution of the family to the thorny ethnographic and development of the Ukrainian nation. The Ivashchenko is a family of Cossack descent with a long history. The earliest news about the existence of the genus dates back to the time of Khmelnytskyi, when, during the National Liberation War of 1648-1657, under the leadership of Bogdan Khmelnytskiy, an independent Cossack state emerged. The name «Ivashchenko» can be found in the register of the Zaporozhian Army in 1649 among the Cossacks of the Pereiaslav regiment. Obviously since then, representatives of this glorious Cossack family lived from generation to generation in the village. Letsky was the Cossack region and even the legends about the founding of the village, connected with the person of the Cossack elder of Letsyk, who, received a land plot near the village of Brovarka and founded a farm. The appearance of the village dates back to the end of the 16th and early 17th centuries, although this territory was inhabited during the times of Kievan Rus
