Lavin
An Irish surname, usually treated as an anglicized form of an old Gaelic family name.
The #5,224 most common surname in the United States (2010 Census) — about 1 in every 46,226 Americans shares it.
Etymology
Lavin is generally explained as an anglicized Irish surname. The Gaelic forms cited by early scholars point to a name built on an old personal name beginning with Fl- or Flaith-, which was reduced and reshaped in English spelling over time. In practice, Lavin is usually treated as a shortened or anglicized descendant of an Irish patronymic rather than a name with a transparent modern-English meaning.
History
The name is strongly associated with western Ireland, especially Mayo and Roscommon in the historical sources provided. Early surname writers also recorded variants such as Lavan and Laven, reflecting the instability of Irish surnames in English documents. By the 19th and 20th centuries, Lavin was established as a recognized Irish family name and later spread through emigration.
