Origin
Meaning and origin of Suplicki
The surname SUPLICKI is of Polish origin, tracing its roots back to the late 15th century in the region of Wielkopolska, situated in west-central Poland. It is believed to have derived from the Polish word "suplika," which translates to "petition" or "request," suggesting that the name may have been associated with individuals involved in administrative or bureaucratic roles.
One of the earliest recorded instances of the SUPLICKI surname can be found in the Metryka Koronna, a collection of official documents from the Polish-Lithuanian Commonwealth, dating back to the late 16th century. The name appears in various spellings, such as "Suplicki," "Suplikowski," and "Suplickiewicz," reflecting the regional variations common in that era.
In the 17th century, a notable figure bearing the SUPLICKI name was Jan Suplicki (1610-1678), a Polish nobleman and military commander who fought in the Smolensk War against Russia. His involvement in this conflict and his service to the Polish Crown earned him recognition and contributed to the prominence of the SUPLICKI name.
During the 18th century, the SUPLICKI surname was associated with the village of Supliki, located in the Lublin region of eastern Poland. This connection suggests a potential link between the name and a specific geographic location, a common occurrence in the development of many surnames.
Another prominent individual with the SUPLICKI surname was Józef Suplicki (1762-1835), a Polish lawyer and political activist who played a significant role in the Kościuszko Uprising against Russian rule in the late 18th century. His involvement in the struggle for Polish independence further elevated the historical significance of the SUPLICKI name.
In the 19th century, the SUPLICKI surname gained recognition through the literary works of Tytus Suplicki (1820-1871), a Polish poet and translator who contributed to the cultural and literary landscape of his time. His literary legacy helped to preserve and propagate the SUPLICKI name across generations.
As the centuries progressed, the SUPLICKI surname continued to be found in various regions of Poland, with individuals bearing this name making contributions in various fields, including academia, politics, and the arts. The name's enduring presence in historical records and its association with notable figures highlights its deep-rooted Polish heritage and the rich tapestry of stories woven into its origin and evolution.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
