Genealogical research in the Sumy region allows us to reconstruct family history using archival documents: identify ancestors, confirm intergenerational relationships, determine family residences, trace migrations, and reconstruct individual biographical details.
Research can span multiple generations and include work with parish registers, confession records, census records, Cossack village lists, censuses, civil registry records, military documents, personal files, educational institution records, judicial, notarial, and other archival sources.

Sumy Oblast is a region with a dual Cossack heritage, making it particularly interesting genealogically. The western and southwestern parts of the region (Glukhov, Konotop, and Krolevets) historically belonged to the Hetmanate, with Glukhov serving as the official residence of the Hetman and the General Military Chancellery for nearly seventy years. The eastern and central parts (Sumy, Akhtyrka, Lebedyn) belonged to Sloboda Ukraine—a region settled by Cossacks fleeing the Right Bank in the 17th century and with its own regimental system, distinct from the Hetmanate's. This juxtaposition of two distinct Cossack traditions directly influences the sources to be sought for a particular family.

The table presents the key stages in the region's administrative history, which are taken into account when determining the collection and archival institution where the relevant documents may be stored.

The research begins with an analysis of the initial data, the historical location of the family, and the identification of sources that may contain information about specific relatives. The work is structured sequentially—from the last reliably known generation to earlier ones, and the transition between generations is documented.

When preparing the research, the following are additionally taken into account:

• historical names of the settlement and their spelling variations;
• administrative affiliation in different periods (Kharkiv, Chernigov, Kursk provinces);
• county, regiment, hundred, volost, and other territorial units;
• religious affiliation of the family;
• Orthodox parish or Old Believer community;
• class affiliation—sloboda or hetmanate Cossacks, peasants, petty bourgeoisie;
• changes in parish and administrative boundaries;
• possible family relocations;
• the presence of settlements with the same name.

Information about a family living in one village may be contained in the records of a parish located in another settlement. Documents from a later period may be stored in the collections of government institutions, while information about education, work, or military service may be stored in other archival complexes.

Historical localization of the family helps to determine a reasonable route of research and not limit the search to only the most obvious sources.

The vast majority of the Sumy region's population has historically been Orthodox, so parish registers and confession records remain the basis for research for most families. However, the region's class structure is significantly more complex than in purely peasant provinces. Here, it is important to consider Cossack origins according to one of two traditions, as well as the presence of Old Believer and Jewish communities in certain settlements.

The following table summarizes the correspondence between class and confession, source types, and search features.

✓ Research of Orthodox peasant and bourgeois families. For such families, the primary sources are parish registers, confession records, and other church records. Birth and baptism dates, marriage and death dates, names of parents and spouses, place of residence, and other information can be determined. Marriage records often include the spouses' ages and origins, which helps trace families back to the previous generation.

✓ Research of Sloboda Cossack families. The Sloboda Cossacks of the Sumy and Akhtyrka regiments had their own registration system, separate from the Hetman's. To research such a family, the regiment and company to which it belonged are determined, and after the 1765 reform that abolished the Sloboda Cossack system, the subsequent class fate of the family is determined, as some Cossacks became commoners in the army, while others retained certain privileges.

✓ Research of the families of the Hetman's Cossacks and elders. The lands around Glukhov and Konotop historically belonged to the Hetmanate, and Glukhov itself was the hetman's residence for a long time. For families originating from this part of the region, in addition to church documents, lists of hundreds, materials from the Rumyantsev inventory of Little Russia, and documents from the General Military Chancellery are important. If the elders' family was subsequently confirmed in the Russian nobility, information about them should be sought in nobility records and genealogical books.

✓ Research of Old Believer families. Old Believer communities were a significant part of the population of certain settlements in the region. Before the legalization of Old Believer registers in the early 20th century, marriages, births, and deaths were often registered through the official Orthodox Church or recorded within the community without state recognition, which complicates the search for early documents.

✓ Research of Jewish families. To research Jewish families, we use birth, marriage, divorce, and death records, as well as administrative, educational, and service documents. For families associated with Sumy, Glukhov, Konotop, and other settlements in the region, it is important to consider spelling variations of first and last names in various documents.

Family history is rarely reconstructed from a single source. The choice of documents depends on the historical period, locality, social class, religious denomination, and the individual's biography.

Sources are selected for a specific research question. If it is necessary to identify a person's parents, birth and marriage documents are examined. If primary birth certificates have not survived, the search continues through alternative materials from the relevant period.

In practice, this sequence is rarely linear. A person's age may vary in different documents, their surname may appear in several spellings, and their family may change their place of residence. To distinguish between people with the same last name, not only the basic data is analyzed, but also godparents at baptism, guarantors at marriage, and other relatives mentioned in nearby documents.

If a family connection cannot be confirmed by documents, it is not replaced by a hypothesis; instead, alternative sources and prospects for continuing the search are analyzed.
The result depends on the integrity of the sources.

This work can establish:

• the full names of ancestors and spelling variations of surnames;
• dates and places of birth, marriage, and death;
• the names of parents and spouses, family composition at different periods;
• class affiliation—sloboda or hetman Cossacks, peasants, petty bourgeoisie;
• places of residence of several generations and directions of migration;
• information about military or Cossack service, property, and inheritance.

The results are systematized to clarify the generational sequence and documentary basis for each established connection. The materials typically include a description of the work performed, copies of the discovered archival documents, archival certificates, and extracts.

Even if only a relative's surname, approximate period of life, and location are known today, a preliminary analysis allows us to evaluate the initial data and determine which categories of archival documents may contain family information.
