Origin
Meaning and origin of Stefankiewicz
The surname Stefankiewicz is of Polish origin, tracing its roots back to the 16th century. It is derived from the Polish given name "Stefan," which means "crown" or "garland." The suffix "-kiewicz" indicates that the name belonged to the son of someone named Stefan.
Stefankiewicz is believed to have originated in the Masovian region of central Poland, where it was first recorded in historical documents from the late 1500s. The name was particularly prevalent in villages and towns around the cities of Warsaw and Płock.
One of the earliest known references to the Stefankiewicz name can be found in the parish records of the Church of St. John the Baptist in Warsaw, dated 1612. This record mentions a Jakub Stefankiewicz, who was a landowner and farmer in the nearby village of Żerań.
In the 17th century, the Stefankiewicz family gained prominence in the Prussian region of Warmia, where they were among the prominent gentry families. A notable member of this branch was Jan Stefankiewicz (1632-1698), who served as a judge and landowner in the town of Olsztyn.
During the 18th century, the Stefankiewicz name appeared in various military records, as several members of the family served in the Polish-Lithuanian Commonwealth's armed forces. One such individual was Michał Stefankiewicz (1712-1783), who fought in the War of the Polish Succession and later became a respected military strategist.
As the Stefankiewicz family spread throughout Poland over the centuries, several variations of the name emerged, including Stefankiewicz, Stefankiewic, and Stefankiewiczówna (for unmarried daughters). Some members of the family also adopted the Polonized version of the name, Stefański.
Notable individuals with the Stefankiewicz surname include:
1. Józef Stefankiewicz (1781-1857), a Polish writer and poet who contributed to the development of Polish Romanticism.
2. Wacław Stefankiewicz (1858-1924), a Polish engineer and inventor known for his contributions to early aviation technology.
3. Anna Stefankiewicz (1891-1972), a Polish painter and art teacher who specialized in portraiture and still-life paintings.
4. Jerzy Stefankiewicz (1914-1997), a Polish actor and theater director, known for his roles in classic Polish plays.
5. Ewa Stefankiewicz (born 1958), a contemporary Polish author and journalist who has written several acclaimed novels and short story collections.

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.

Keep in mind that these are self-reported numbers.
