Marsh
A topographic surname for someone who lived by or on marshy, low-lying ground.
The #537 most common surname in the United States (2010 Census) — about 1 in every 4,955 Americans shares it.
Etymology
Marsh comes from Old English mersc, meaning a marsh, bog, or wet lowland. It was first used for people identified by where they lived, especially beside wet ground or reclaimed marshland. In this sense, it is a classic English topographic surname.
History
The name appears widely in medieval England and remained common because many families were identified by local landscape features. Historical records also show related forms such as in the Merche, reflecting the same marsh-based meaning. The surname later spread through Britain and then to North America and other English-speaking regions.
