Origin
Meaning and origin of Blazejewski
The surname Blazejewski is of Polish origin, deriving from the given name Blazej, which is the Polish version of the name Blaise or Blasius. This name can be traced back to the Latin name Blasius, which means "lisping" or "stammering."
The Blazejewski surname is believed to have originated in the late Middle Ages or early Renaissance period, likely between the 14th and 16th centuries. It was most commonly found in the regions of Greater Poland, Silesia, and Pomerania, which were part of the historical Polish territories.
One of the earliest recorded instances of the Blazejewski surname can be found in the Tarnow land records from the 16th century, where a landowner named Jan Blazejewski is mentioned. Another early reference is in the parish records of the town of Krajenka in Greater Poland, where a Blazejewski family is recorded as living in the 17th century.
In the 18th century, a notable figure with the Blazejewski surname was Józef Blazejewski (1735-1797), a Polish nobleman and landowner from the Kalisz region. He was a prominent member of the local gentry and served as a judge in the local court.
During the 19th century, the Blazejewski name gained recognition through the work of Franciszek Blazejewski (1810-1876), a Polish writer and poet who authored several collections of poetry and prose works. He was born in the town of Opalenica in Greater Poland and is considered an important figure in the Polish Romantic literary movement.
Another noteworthy individual with the Blazejewski surname was Wacław Blazejewski (1836-1911), a Polish-born painter and art professor who spent much of his career in Dresden, Germany. He was known for his landscapes and genre paintings, and his works can be found in several museums and galleries across Europe.
In the early 20th century, Stanisław Blazejewski (1870-1939) was a Polish engineer and inventor who made significant contributions to the development of early aircraft design. He was born in the town of Kruszwica and worked on various projects related to aeronautics and aviation technology.
While the Blazejewski surname has its roots in Poland, it has also been found in other Slavic countries, such as Belarus and Ukraine, likely due to migration and intermarriage between these regions over the centuries.

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.
