Lay
A surname that may come from a lane in the forest or from the word for “lay” or “unclerical,” with some cases also tied to Irish or Scottish surname forms.
The #1,957 most common surname in the United States (2010 Census) — about 1 in every 16,718 Americans shares it.
Etymology
The surname Lay has more than one possible source. In English and Anglo-French it may come from Old French laie, meaning a lane or path through a forest, or from Middle English lay, meaning “not clerical” or “unlearned.” Some records also point to it as a shortened or altered form of Gaelic surnames such as Mac Leay or Mac Lay, especially in Scottish usage. Because these lines of origin overlap, the name is best treated as a surname with several independent sources rather than a single fixed derivation.
History
The name appears in medieval and later records in England, and Lower notes forms such as H.R. Le Lay, Du Lay, and De Lay, showing that it also existed with French-style prefixes. In Scottish material, writers such as Harrison connect Mac Lay with Lay or Leay-type forms, suggesting anglicized or reduced Gaelic surnames. As with many short surnames, separate families may share the same spelling without sharing the same ancestry.

Fun fact
Because “lay” could mean either a forest lane or a non-clerical person, the same surname spelling may have arisen from completely different meanings in different places.
