Vail
Usually a surname for someone who lived in a valley, though it can also reflect spelling variation from related names.
The #3,385 most common surname in the United States (2010 Census) — about 1 in every 29,254 Americans shares it.
Etymology
The main explanation in the sources is that Vail is a topographic surname meaning “dweller in a vale” or valley. It goes back to Middle English vale, from Old French val, ultimately from Latin vallis, “valley.” Some later writers also treated Vail as a spelling or pronunciation variant of other surnames, especially in Anglo-French and Irish contexts, so the name can have more than one historical pathway.
History
Medieval records in England already show forms such as de Vail, indicating an early place-based surname. Over time, spellings varied among Vale, Vail, Vaile, and Vaill, with many families likely adopting the form that suited local pronunciation or scribal habit. The name is also noted in some Irish surname references as a variant spelling found alongside MacVail and related forms.
