Keener
An English-language surname that likely began as a nickname for someone sharp, shrewd, or keen-witted.
The #2,633 most common surname in the United States (2010 Census) — about 1 in every 22,558 Americans shares it.
Etymology
Keener is most likely from the adjective keen, meaning sharp, eager, or quick-minded, with the surname formed as a nickname or descriptive byname. The word goes back to Old English cēne, meaning bold, brave, or keen, though later English usage also emphasized sharpness of mind or perception. The final -er can mark a comparative or be part of surname formation, so the name may have started as a descriptive label rather than an occupation.
History
The name appears in English-speaking records as a surname and also shows up in American surname lists from the 19th century. It is less common than the base form Keen, and in some families it may also reflect later spelling variation or anglicization of related names. Because the available excerpts only mention it in passing, the exact line of descent for particular bearers is uncertain.

Fun fact
The same adjective behind Keener also produced surnames like Keen and even comparative-looking forms such as Kearney in some traditions, though those names are not all related.
