The history of the last name Zadlo

The surname Zadlo has its origins in Central Europe, specifically Poland. The name first emerged in the medieval period, around the 14th or 15th century. The regions it is most commonly associated with include Lesser Poland and the historical region of Galicia. The surname could be derived from the old Polish word "zadłużyć," which means to become indebted, or it could have connections to occupational terms or geographical features yet to be definitively traced.

Old records and historical manuscripts frequently listed surnames, especially in the context of taxation, land ownership, and court cases. The surname Zadlo first appeared in written form in a tax record from Kraków in 1452. This makes it relatively early in the timeline of Polish surnames becoming hereditary and consistently used within families.

One of the earliest recorded individuals with this name was a certain Jan Zadlo, a landowner in the village of Bochnia in 1478. Another notable figure was Katarzyna Zadlo, a widow mentioned in a court document from 1505, indicating she was involved in a land dispute in the vicinity of Tarnów. These instances highlight the surname's deep historical roots and show it was established across various small communities.

In 1596, records from the town of Wieliczka documented a Bartłomiej Zadlo, a salt mine worker, suggesting that the name was not only associated with landowners but also with the working class in these regions. Additionally, the name appeared in religious texts, such as parish records, with individuals like Mikołaj Zadlo being recorded as a parish clerk in Kraków in the early 1600s.

Fast-forwarding to the 18th century, the name appears again with notable individuals like Stanisław Zadlo, born in 1713, an educator who contributed significantly to the local schools in Przemyśl until his death in 1781. Also of note was Krzysztof Zadlo, who served as a town council member in Lwów in the mid-1700s, recorded in municipal records dating to 1754.

Through these documented instances, the surname Zadlo reflects a diverse array of professions and social standings, grounding it firmly in Polish history. Its etymology, tied closely to the Old Polish language and regional dialectics, enriches its historical tapestry.
