Langan
A surname often linked to place-names, especially as a form related to “long” or to church-land names in Gaelic and Cornish areas.
The #6,769 most common surname in the United States (2010 Census) — about 1 in every 61,972 Americans shares it.
Etymology
The name is usually treated as locational, but its exact derivation is not fully settled. One line of explanation connects it with Cornish place-name forms involving lan - or lang- elements, with the old Cornish word for a church or sacred enclosure and with forms glossed as “long” in place-names. Irish and Gaelic surname tradition also shows Langan alongside related forms such as Longan and Lanigan, suggesting more than one regional source may have fed the modern surname.
History
The surname appears in medieval and later records in Ireland and Britain, and nineteenth-century writers already treated it as a name with overlapping local and Gaelic explanations. In Irish contexts it is often discussed with related forms like Lanigan and Longan, while Cornish scholarship linked it to local place-name elements and parish names. Because the surname occurs in more than one region, modern bearers may not share a single origin.

Fun fact
Early surname scholars sometimes grouped Langan with other names beginning with Lan- because the underlying place-name evidence was hard to separate cleanly.
