Lair
A rare surname that may reflect a place name or, in some cases, a descriptive term related to a den or shelter.
The #8,425 most common surname in the United States (2010 Census) — about 1 in every 78,701 Americans shares it.
Etymology
The surname Lair is not securely established from the excerpted sources, and it may have more than one origin. In English and Dutch contexts, it could be locational, tied to words meaning a den, hollow, or sheltered place; some older writers also compare it with place-name forms such as Laer or Van Eensselaer. The Irish material points to confusion with Gaelic names beginning Mac Laire/Mac Lave, while the French notes show unrelated common nouns, so the surname may have arisen independently in different places.
History
The name is uncommon in the United States and appears in historical discussion mostly as a difficult or marginal surname rather than a well-attested major family line. Some 19th-century surname writers grouped it with place-based names ending in -lair or -laer, while Irish scholarship suggests possible overlap with anglicized Gaelic forms. Because the sources are incidental and not a single clean headword entry, the surname’s history is best treated as mixed and uncertain.

Fun fact
One of the cited references connects Lair with words for a den, cave, or burrow, showing how easily a surname can be mistaken for an ordinary noun in old lexical works.
