Kubiak

Etymology
Kubiak is a Polish surname built from the personal name Kuba, a familiar form of Jakub, the Polish equivalent of Jacob. The suffix -iak is common in Polish surnames and often indicates descent, association, or origin, so the name can be understood as "son of" or "belonging to" Kuba. In practice, it is a patronymic surname formed from a nickname or diminutive of a biblical given name.
History
The surname is especially associated with Poland and Polish-speaking communities, and it became more widely visible through emigration to North America and other countries. Like many Polish surnames, it likely arose independently in more than one place from the same naming pattern. In the United States it is relatively uncommon but clearly established among families of Polish ancestry.
