Origin
Meaning and origin of Macioch
The surname Macioch is of Polish origin, with its earliest known records dating back to the 16th century. It is derived from the Polish word "maciocha," which means "stepmother" or "mother-in-law." This suggests that the name may have originated as a descriptive nickname for someone with a stepmother or a mother-in-law.
One of the earliest recorded instances of the name Macioch can be found in the historical documents of the Lublin region in eastern Poland, where it was spelled as "Maczyoch." This variation in spelling was common during that time period, as standardized spellings were not yet established.
In the 17th century, the name Macioch appeared in the records of the town of Kazimierz Dolny, located in the Lublin Voivodeship. This town was a prominent center of trade and craftsmanship, and it is possible that some individuals bearing the name Macioch were involved in these industries.
Notably, there is a record of a Wojciech Macioch, who lived in the town of Janowiec in the Lublin region during the late 16th century. He was a landowner and a member of the local nobility, indicating that the name Macioch had spread beyond its humble beginnings as a descriptive nickname.
In the 18th century, the name Macioch gained wider recognition with the birth of Franciszek Macioch (1749-1823), a Polish poet and playwright. He was born in the village of Wojkowice near Krakow and is best known for his satirical works that commented on the social and political issues of his time.
Another notable figure with the surname Macioch was Stanisław Macioch (1870-1945), a Polish painter and art educator. He was born in the town of Łęczyca and studied at the Academy of Fine Arts in Krakow. Macioch's works often depicted scenes from rural life and landscapes, reflecting his deep connection to his Polish heritage.
During the 19th and 20th centuries, the name Macioch continued to be prominent in various regions of Poland, with individuals bearing this surname contributing to various fields, including academia, literature, and the arts.

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.
