Origin
Meaning and origin of Hryniewicz
The surname Hryniewicz is of Polish origin, deriving from the personal name Hryn, which is a diminutive form of the Slavic name Hryhor or Grzegorz, equivalent to the English name Gregory. The name likely emerged in the late medieval period, around the 14th or 15th century, in the regions of present-day Poland.
The earliest recorded instances of the surname Hryniewicz can be traced back to historical records and documents from the 16th century in the Polish-Lithuanian Commonwealth. One notable mention is found in the Metryka Koronna, a collection of royal decrees and charters from the Polish Crown, where a certain Jan Hryniewicz is listed as a landowner in the Podlasie region in the year 1589.
In the 17th century, the Hryniewicz name appears in various parish records and tax registers across different regions of Poland, indicating its spread and establishment as a distinct surname. One such example is a record from the town of Łomża in Masovia, where a family by the name of Hryniewicz is listed among the local nobility in 1643.
During the 18th century, the Hryniewicz surname gained further prominence, with several notable individuals bearing this name. One such figure was Jakub Hryniewicz (1714-1783), a Polish Catholic priest and theologian who served as a professor at the Jesuit College in Vilnius, Lithuania.
In the 19th century, the Hryniewicz surname continued to be well-represented in various fields. Aleksander Hryniewicz (1825-1901) was a Polish writer and journalist who published several works on Polish history and culture. Another notable bearer of this name was Franciszek Hryniewicz (1858-1932), a Polish engineer and industrialist who played a significant role in the development of the textile industry in the Łódź region.
Moving into the 20th century, one prominent figure with the Hryniewicz surname was Wacław Hryniewicz (1936-2020), a Polish Catholic theologian and ecumenist who made significant contributions to the dialogue between the Catholic Church and other Christian denominations.

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.
