Finnerty
An Irish surname, most likely an anglicized form of a Gaelic name linked to the root fin- meaning “fair” or “white.”
The #8,184 most common surname in the United States (2010 Census) — about 1 in every 76,196 Americans shares it.
Etymology
Finnerty is generally treated as an Irish surname derived from Gaelic forms built on the element fin-, meaning “fair,” “white,” or “bright.” In older Irish naming practice, such forms often developed into surnames by adding a patronymic ending, so the name likely began as a descriptive or family-based Gaelic byname before being anglicized. The exact original Gaelic form is not entirely settled in the older sources, and 19th-century writers often grouped Finnerty with several similar-looking Irish surnames.
History
The surname is especially associated with Ireland, and historical sources place it notably in Connacht, including Galway. By the 19th century it was already established in Irish and Irish-American records, and Bowditch lists it among names then current in Boston. Variant spellings such as Finerty and Fannerty reflect normal anglicization and recording differences.
