Clemmer
A surname most likely from a medieval personal name, probably a short form of Clement.
The #9,446 most common surname in the United States (2010 Census) — about 1 in every 89,647 Americans shares it.
Etymology
Clemmer is most likely a nickname or surname formed from the personal name Clement, ultimately from Latin Clemens, meaning "gentle" or "merciful." In English and some neighboring surname traditions, short forms of given names often developed into hereditary surnames by adding familiar endings such as -er. The ending in Clemmer may reflect regional pronunciation or later spelling variation rather than a distinct original root.
History
As with many surnames built from personal names, Clemmer would have arisen independently in more than one place from a bearer named Clement or a close diminutive of that name. The spelling is especially associated with Anglophone surname development in Britain and North America, where clerks often recorded names in variant forms. It is less common than Clement, Clemens, or Clemmons, but follows the same broad naming pattern.
