Origin
Meaning and origin of Kortokrax
The surname "KORTOKRAX" traces its origins to a small village in the mountains of northern Bulgaria, situated in the region known as the Rhodope Mountains. This area has a rich history dating back to ancient Thracian times and has been influenced by various cultural groups over the centuries, including Slavic, Greek, and Turkish populations.
The name "KORTOKRAX" is believed to have derived from an old Thracian word meaning "steep rocky path" or "mountain pass." This etymology reflects the rugged terrain of the region where the name originated. The earliest known written records of the surname date back to the 16th century, when it appeared in local church registers and land ownership documents.
One of the earliest recorded instances of the name "KORTOKRAX" can be found in a Bulgarian manuscript from the late 16th century, which details the settlement of a family bearing this surname in the village of Chepelare. This manuscript provides valuable insights into the lives and traditions of the early bearers of the name.
In the 17th century, a notable figure named Ivan KORTOKRAX (1623-1689) gained recognition as a skilled artisan and woodcarver. His intricate works adorned several churches and monasteries in the region, showcasing the craftsmanship that ran in his family's lineage.
During the 18th century, the name "KORTOKRAX" became associated with a prominent family of merchants and traders from the town of Smolyan. One member, Georgi KORTOKRAX (1742-1812), established a successful trading company that facilitated the exchange of goods between the Rhodope Mountains and the larger cities of the Ottoman Empire.
Another significant figure bearing the "KORTOKRAX" surname was Mariya KORTOKRAX (1857-1932), a renowned herbalist and healer from the village of Shiroka Laka. Her knowledge of traditional medicinal plants and remedies was highly respected throughout the region, and she trained several apprentices to carry on her legacy.
In the early 20th century, a scholar and linguist named Petar KORTOKRAX (1891-1968) made significant contributions to the study of Thracian language and culture. His research and publications helped to preserve the rich linguistic heritage of the Rhodope Mountains and shed light on the ancient roots of the "KORTOKRAX" name.
While the surname "KORTOKRAX" may not be as widely known as some other Bulgarian surnames, it holds a special place in the cultural tapestry of the Rhodope Mountains region. Its enduring presence over centuries serves as a testament to the resilience and adaptability of the families who have carried this name through generations.

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.

Keep in mind that these are self-reported numbers.
