Fleck
A surname that can come from a nickname for something spotted or from related continental name forms.
The #4,012 most common surname in the United States (2010 Census) — about 1 in every 34,879 Americans shares it.
Etymology
The surname Fleck is most often linked to a word meaning a spot, speck, or blotch, which would make it a descriptive nickname for someone with a speckled appearance, clothing, or perhaps a marked characteristic. Some older surname writers also connect it with related Germanic forms and with Dutch or German names such as Vlak or Vleck, showing how similar surnames could cross languages and spellings. Because the historical evidence is not tidy, the exact source of any one family line may differ by region.
History
The name appears in several spelling traditions across Britain and northern Europe, and historical surname writers treated it as connected with a cluster of similar forms rather than a single fixed origin. In Scotland, related names like Affleck were sometimes discussed alongside local place-name explanations, but Fleck itself is not always clearly separable from those wider surname families. The spelling has remained fairly stable in English-speaking countries, though it is not a very common surname.

Fun fact
In older surname studies, Fleck was sometimes grouped with names that simply meant a 'spot' or 'speck,' showing how ordinary visual details could become hereditary surnames.
