Register of the Sumy regiment of 1660

The 1660 register of the Sumy Cossack regiment is a unique document that reflects the personal composition of the regiment at the beginning of its formation. Compiled by order of Colonel Gerasim Kondratiev, this register contains a detailed list of Cossacks and townspeople who lived on the territory of the regiment after the defeats at Varva and Pisky. The document allows researchers to reconstruct family ties, the social and economic status of the population, and also reveals the migration processes of those times. Special attention is drawn to various surnames, which testify to the wide geographical spectrum of immigrants to Slobozhanshchyna.
