Origin
Meaning and origin of Mramor
The surname MRAMOR originated in Croatia, with records dating back to the late 16th century. It is derived from the Croatian word 'mramor', meaning marble. The name likely referred to an early bearer's occupation as a marble worker or someone living near a marble quarry.
The earliest known record of the MRAMOR surname appears in the parish registers of the village of Brač, located on the Adriatic island of the same name, in 1587. This island was renowned for its high-quality marble quarries, which were actively mined during the Renaissance period.
In the 17th century, the MRAMOR name spread to other regions of Croatia, particularly the coastal areas and islands where marble quarrying was a prominent industry. Variations in spelling, such as Mramorov and Mramorich, can be found in historical documents from this era.
One notable early bearer of the MRAMOR name was Ivan Mramor, a master stonemason who lived in the town of Korčula in the late 1600s. He is credited with the construction of several prominent buildings, including the Church of St. Mark, which features intricate marble carvings.
The MRAMOR surname also found its way into the historical records of neighboring countries, such as Italy and Slovenia, likely due to migration and trade. In the 18th century, a branch of the family settled in the Venetian Republic, where a Giovanni Mramor is mentioned in the city archives of Trieste in 1734.
During the 19th century, several individuals with the MRAMOR surname achieved notable positions. Josip Mramor (1803-1878) was a respected scholar and writer from Zagreb, who published works on Croatian history and literature. His contemporary, Marko Mramor (1819-1891), served as a high-ranking military officer in the Austro-Hungarian Empire.
Other prominent bearers of the MRAMOR name include Petar Mramor (1865-1923), a successful entrepreneur and philanthropist from Split, and Katarina Mramor (1892-1967), a celebrated opera singer who performed throughout Europe in the early 20th century.

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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Mramor surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
