Finley
An anglicized Irish and Scottish surname that often began as a form of Finlay or a name built from Gaelic fin, “fair” or “white.”
The #922 most common surname in the United States (2010 Census) — about 1 in every 8,196 Americans shares it.
Etymology
Finley is usually treated as an anglicized form of Gaelic surnames such as Mac Fhionnlaigh or related names rendered in English as Finlay. The first element is Gaelic fionn, meaning “fair,” “white,” or “pale,” while the second element is commonly understood as a personal-name element of uncertain or debated origin in older scholarship. In practice, Finley and Finlay have long overlapped in spelling and pronunciation, especially in Lowland Scottish and Irish usage.
History
The surname spread into English through the movement of Scottish and Irish families and through the many spelling changes that accompanied Anglicization. Nineteenth- and early twentieth-century surname writers often grouped Finley with Finlay, Fenley, and related forms as variant renderings of the same Gaelic name. In North America it became established as a fairly common family name, with spellings often shifting from one generation to the next.
