Merrill is usually an English surname from a medieval personal name, often treated as a form of Muriel or Meriel, though some sources also connect it to older Germanic roots meaning “famous” or even “sea.”
The #1,073 most common surname in the United States (2010 Census) — about 1 in every 9,465 Americans shares it.
Etymology
The surname Merrill is generally explained as coming from a medieval given name, especially Meriel or a related French form. One common line of explanation makes it a pet or shortened form of Muriel/Meriel. Harrison also notes possible deeper roots in Germanic elements meaning “famous” or in words for “sea,” but treats these as alternative possibilities rather than a single settled derivation.
History
English records show several spellings such as Merrell, Merret, and Merrill, reflecting the name’s shifting medieval pronunciation. By the 19th century, writers were already noting that Merrill could be heard or written as Meriel or Merrell, and American surname directories list it as established in the United States. The name has been especially visible in English-speaking countries, including Britain and the U.S.
