Cronk
A surname with more than one possible root, but most likely a place-name form linked either to a hill word or to a “crooked” nickname element.
The #6,260 most common surname in the United States (2010 Census) — about 1 in every 56,588 Americans shares it.
Etymology
The name is probably best understood as a surname from a place name or a descriptive nickname. In Manx, cronk means “hill,” and the Manx source excerpt notes that it is a later form related to the older Gaelic word cnoc, also meaning “hill.” Other English surname work points to Cronk as a local-name form, and another tradition connects Cronk- with a Germanic element meaning “crooked,” appearing in related spellings such as Crank-, Crink-, and Crunk-.
History
The surname appears in English and Manx contexts, especially in areas where local topography shaped surnames. The Manx evidence makes clear that cronk was a living common noun in the Isle of Man, which could easily have generated habitational or topographic surnames. Because the surname may reflect either Manx hill-names or an English/Germanic “crooked” element, its history is best treated as mixed rather than single-origin.

Fun fact
In Manx place-names, cronk is so common that it appears in hill names like Cronk-ny-arrey-Lhaa, literally a “hill of the watch by day.”
