Leath
An old surname that likely began as a nickname or local name, with possible links to meadowland or an ancient personal name.
The #9,628 most common surname in the United States (2010 Census) — about 1 in every 91,562 Americans shares it.
Etymology
The surname Leath has more than one plausible explanation in the old surname books. One line of interpretation connects it with a place-name in Cumberland/Westmorland, referring to a ward or district called Leath; another links it to an Old English word seen in forms like lyth/leth, meaning mild or gentle, which could have produced a nickname. The evidence is not decisive, so the surname is best treated as having an uncertain origin with both locational and descriptive possibilities.
History
Lower treated Leath as the name of a Cumberland ward, while Bardsley also associated it with a Yorkshire place-name glossed as “the meadow by the barn.” The name appears in English records as both a surname and a place-related designation, and it seems to have spread as families moved away from the original locality. In older scholarship it was also grouped with names derived from an early personal name, Lethar.

Fun fact
19th-century surname writers sometimes linked Leath with the same word-family as names like Leather, showing how freely they moved between place-names, nicknames, and ancient personal names.
