Origin
Meaning and origin of Slusarz
The surname SLUSARZ is of Polish origin, originating in the late medieval period. It is derived from the Polish word "sluzarz," which translates to "locksmith" or "gunsmith." This occupation-based surname likely referred to someone who worked as a metalsmith, crafting locks, keys, or firearms.
The name can be traced back to the 14th century, appearing in various historical records and manuscripts from that era. One notable early mention is found in the "Księga Ziemska Krakowska" (The Land Book of Krakow), a register of land ownership and transactions in the Krakow region, dating back to the late 1300s.
One of the earliest recorded individuals with the surname SLUSARZ was Jan SLUSARZ, a prominent locksmith who lived in the city of Krakow in the late 15th century. His works and craftsmanship were highly regarded, and he is mentioned in several accounts from that time.
Another notable figure was Stanislaw SLUSARZ, a skilled gunsmith who lived in the town of Tarnow in the mid-16th century. He was renowned for his expertise in crafting firearms and was commissioned by local nobility and military leaders.
In the 17th century, the name SLUSARZ appeared in the historical records of the town of Poznan, where a family of locksmiths and metalsmiths bearing this surname had established a successful business. One member, Marcin SLUSARZ (1620-1689), was particularly renowned for his intricate and ornate lockwork.
During the 18th century, the SLUSARZ surname gained prominence in the city of Warsaw, where a family of gunsmiths and metalworkers bearing this name had settled. Jakub SLUSARZ (1725-1801) was a highly skilled gunsmith who supplied firearms to the Polish military and nobility.
In the 19th century, the SLUSARZ name was also found in the records of the town of Lodz, which had become a center of industry and metalworking. Franciszek SLUSARZ (1845-1912) was a respected locksmith and metalworker who contributed to the city's growing industrial landscape.
Throughout its history, the surname SLUSARZ has been associated with the skilled trades of metalworking, locksmithing, and gunsmithing. While the name has its roots in Poland, it has since spread to various other regions and countries due to migration and diaspora.

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.
