Elmer is a name of Germanic British origin. The given name originated as a surname, a medieval variant of the given name Aylmer, derived from Old English æþel (noble) and mær (famous). It was adopted as a given name in the United States, "in honor of the popularity of the brothers Ebenezer and Jonathan Elmer, leading supporters of the American Revolution." The name has declined in popularity since the first decades of the 20th century and fell out of the top 1,000 names used for American boys in 2009. However, it continues in use for newborn boys in the United States, where 154 boys born there in 2021 received the name. The name is common in the United States and Canada.
