Origin
Meaning and origin of Tomlanovich
The surname Tomlanovich originates from the Slavic regions of Eastern Europe, with roots dating back to the late medieval period, around the 15th century. It is believed to have originated in the areas that now encompass parts of modern-day Croatia, Serbia, and Bosnia and Herzegovina.
The name Tomlanovich is derived from the Slavic personal name "Tomlan," which itself is a diminutive form of the name "Tomislav." The suffix "-ovic" or "-ovich" is a common patronymic ending in Slavic surnames, indicating "son of." Thus, Tomlanovich would have originally referred to the son or descendant of a person named Tomlan.
Historical records from the region suggest that the name Tomlanovich first appeared in written documents during the latter half of the 15th century, though it may have been in use orally for some time before that. One of the earliest known references to the name can be found in a chronicle of the Dubrovnik Republic, dated around 1480, which mentions a merchant named Mihovil Tomlanovich.
As the name spread across the Slavic lands, it underwent various spelling variations, such as Tomlanovic, Tomljenovics, and Tomlyanovich, reflecting regional linguistic differences and the influence of different scribes and record-keepers.
Several notable individuals have borne the surname Tomlanovich throughout history:
1. Nikola Tomlanovich (c. 1620 - 1685), a Serbian Orthodox priest and writer who authored several religious texts and translations.
2. Stjepan Tomlanovich (1768 - 1844), a Croatian military officer who served in the Austrian Empire's army during the Napoleonic Wars.
3. Marija Tomlanovich (1852 - 1932), a Serbian painter and one of the pioneering female artists from the region, known for her portraits and landscapes.
4. Ivan Tomlanovich (1882 - 1962), a Croatian-American engineer who played a significant role in the construction of several notable bridges and infrastructure projects in the United States.
5. Jovan Tomlanovich (1920 - 2001), a Serbian-born American physicist and academic, known for his contributions to the study of solid-state physics and semiconductor devices.
While the Tomlanovich name has its roots in Eastern Europe, it has since spread to various parts of the world through migration and diaspora communities, carrying with it a rich cultural heritage and history.

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.
