Etymology
Flanigan is an Anglicized form of the Irish surname Flanagan, with variant spellings such as Flanigan, Flannigan, and Flanagin. The name is generally traced to Gaelic elements built on flann, meaning “red” or “ruddy,” with a diminutive or family-name ending, so the sense is roughly “descendant of the red-haired/ruddy one.”
History
The surname is especially associated with Ireland and Irish diaspora communities, where English spelling often varied widely in records. Historical dictionaries group Flanigan with Flanagan and related spellings rather than treating it as a separate name, which reflects the fluid spelling of Irish surnames in the 19th and early 20th centuries.
