The history of the last name Onderko

The surname Onderko is believed to have originated in the Czech Republic during the late medieval period, likely in the 14th or 15th century. It is derived from the Czech word "ondra," which is a diminutive form of the name Ondřej, the Czech equivalent of Andrew. The suffix "-ko" was commonly added to names in this region to indicate a diminutive or familial form.

The earliest known record of the Onderko surname can be found in a document from the town of Jičín, located in the modern-day Královéhradecký Region of the Czech Republic, dated to the year 1487. This document mentions a "Jan Onderko" as a landowner in the area.

During the 16th and 17th centuries, the Onderko name appeared in various records and manuscripts across Bohemia and Moravia, which were part of the Kingdom of Bohemia at the time. One notable example is the mention of a "Matěj Onderko" in the records of the city of Olomouc, dated to 1623.

In the 18th century, a branch of the Onderko family settled in the village of Újezd, now part of the city of Brno. This is evidenced by the birth record of a "Václav Onderko" in 1734, whose descendants continued to reside in the area for several generations.

One of the earliest known individuals with the Onderko surname was Jan Onderko (1670-1742), a prominent merchant and landowner in the town of Kutná Hora. Another notable figure was Jakub Onderko (1785-1861), a respected teacher and writer who authored several books on Czech grammar and literature.
