Origin
Meaning and origin of Modrich
The surname MODRICH is of Croatian origin, tracing its roots back to the medieval period in the region now known as Croatia. It is believed to have originated as a toponymic surname, derived from the name of a place or geographic location.
One possible theory suggests that the name MODRICH may have evolved from the Slavic word "modry," meaning "blue" or "green." This could indicate that the name was initially associated with a person who lived near a body of water with a distinct blue or greenish hue, such as a lake or river.
Another hypothesis proposes that MODRICH may be linked to the Croatian word "modar," which translates to "bruise" or "contusion." This could signify that the name was initially bestowed upon an individual who sustained a notable injury or had a distinctive physical characteristic related to bruising.
Historical records from the 14th century mention individuals bearing the MODRICH surname in the Croatian regions of Dalmatia and Slavonia. One of the earliest documented instances is found in a manuscript from 1347, which refers to a certain Petar MODRICH, a landowner in the village of Modric near the city of Zadar.
In the 16th century, a prominent figure named Nikola MODRICH (1528-1592) gained recognition as a skilled navigator and cartographer. He is credited with creating detailed maps of the Adriatic Sea and the eastern Mediterranean region, which were widely used by sailors and merchants during that era.
The 17th century saw the rise of Ivan MODRICH (1617-1688), a renowned Croatian architect who played a significant role in the construction of several notable buildings in the cities of Split and Trogir. His most celebrated work is the Cathedral of St. Lawrence in Trogir, which is a masterpiece of Renaissance architecture and a UNESCO World Heritage Site.
In the 19th century, a Croatian writer and poet named Ante MODRICH (1819-1878) gained literary acclaim for his contributions to the development of the Croatian language and literature. His poems and works celebrating Croatian cultural heritage and national identity were influential during the Croatian National Revival movement.
Another notable figure was Marija MODRICH (1878-1947), a Croatian educator and women's rights activist who fought for equal educational opportunities for girls and women in the early 20th century. She established several schools and educational institutions, leaving a lasting impact on the advancement of women's education in Croatia.

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 Modrich surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

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