✓ Research of Greek Catholic families. For Greek Catholic families, the primary sources are parish registers, which recorded baptisms, marriages, and deaths. These records allow one to determine dates of birth and baptism, marriage and death, the names of parents and spouses, place of residence, and other information.
Marriage records can be particularly valuable for further research—they often contain the ages of the spouses and information about their origins, allowing one to move back to the previous generation or find a new direction. Information about godparents and witnesses at marriages can provide additional information, helping to distinguish between people with the same last name, especially in large villages.
✓ Research of Roman Catholic families. To find information about a Roman Catholic family, it is necessary to determine the parish to which the ancestral settlement belonged during the period under study, as not every village had its own church.
In such cases, birth, marriage, and death records should be sought in the records of a parish serving several localities. If one of the spouses hailed from a different parish or region, the corresponding family line is researched based on their place of origin, including, if necessary, archives in present-day Poland.
✓ Research of families of the Armenian community. Lviv. The Armenian community of Lviv had its own rite and maintained separate registers, making such families a special area of research. Establishing affiliation with the Armenian community requires specifying the specific parish and period, as well as verifying whether the family subsequently adopted a different rite.
✓ Research of Jewish families. Birth, marriage, divorce, and death records, as well as administrative, tax, educational, and service documents, are used to research Jewish families. It is important to consider spelling variations of first and last names—the same person may appear in different documents under different forms of first name, patronymic, or last name, recorded in different languages.
For families with ties to Lviv, Drohobych, Zhovkva, Brody, and other settlements in the region, birth records may be supplemented by documents containing information on family composition, place of residence, occupation, education, and relatives' movements. A significant portion of pre-war documents were lost or displaced in the 20th century, so the search often requires consulting multiple archival institutions, including those abroad.
