It traces back to the medieval period, around the 12th or 13th century. The name is believed to be derived from the Old Germanic word "wulkan," meaning "volcano" or "fire." This connection likely refers to a person's occupation or a geographical feature near where they lived.
Historical references to the surname Wulkan can be found in various medieval documents and records.

In the 17th century, the name appears in the context of religious and political conflicts. Samuel Wulkan, born in 1643, was a notable soldier who fought in the wars between Poland and Sweden. His military service is detailed in regimental ledgers and personal letters preserved in Polish archives.
By the 18th century, the name had spread to various parts of Europe due to migration and trade. Johan Wulkan, born in 1720, is recorded as a farmer and local council member in Brandenburg, Germany.

Demographics
Among Census respondents with the surname Wulkan, the largest self-reported group is White at 100.0%.
The bar chart below shows how Wulkan bearers described their own race and ethnicity on the 2020 Census form. 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 Wulkan surname at the time of the 2020 Census, not any inherent property of the name itself.
