Origin
Meaning and origin of Mikolich
The surname Mikolich is of Croatian origin, originating from the Dalmatian region of Croatia. It likely has its roots in the Slavic word "miko," which means "small" or "little." This suggests that the name may have been initially used as a nickname or descriptive name for someone of small stature.
The earliest known records of the surname Mikolich date back to the 16th century in the coastal town of Zadar, which was part of the Venetian Republic at the time. The name appears in various forms, such as Mikolich, Micolich, and Mikulich, in historical documents and parish records from that period.
One of the earliest recorded individuals with the surname Mikolich was Petar Mikolich, a merchant and ship owner from Zadar, who lived in the late 16th century. Another notable figure was Ivan Mikolich, a prominent lawyer and judge in Zadar during the 17th century.
In the 18th century, the surname Mikolich can be found in the records of the Venetian naval forces, with several individuals bearing this name serving as sailors and officers. One such individual was Antun Mikolich, a naval captain who participated in the Battle of Lepanto in 1571 against the Ottoman Empire.
As the Croatian population migrated and settled in various parts of Europe and the Americas, the surname Mikolich spread to other regions. In the 19th century, there are records of individuals with this surname living in parts of Italy, Austria, and the United States.
One notable individual from this period was Marko Mikolich, a Croatian businessman and philanthropist who lived in Vienna, Austria, in the late 19th century. He was known for his contributions to various charitable organizations and his support for Croatian cultural initiatives.
Another significant figure was Josip Mikolich, a Croatian-American artist and painter who was born in 1868 in the town of Slavonski Brod, Croatia. He immigrated to the United States in the late 19th century and became known for his landscape and portrait paintings, exhibiting his works in several galleries across the country.
While the surname Mikolich is not among the most common Croatian surnames, it has a rich history and has been carried by individuals from various walks of life throughout the centuries, from merchants and sailors to lawyers, artists, and philanthropists.

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.
