Seamour is English in Origin.

Seamour is a modern respelling of the English given name and surname Seymour, of Norman French origin. The surname arose from families identified with Saint‑Maur in Normandy (French Saint-Maur, from Latin Sanctus Maurus). In English, it later blended with a place‑name sense - sea + moor - yielding the folk meaning “marshland by the sea.” Thus Seamour can be understood as “of Saint-Maur” or “sea moor,” while retaining the classic SEE‑mor pronunciation.

Used as a surname in medieval England, the name became prominent through the Tudor-era Seymours - most notably Jane Seymour, third wife of Henry VIII, and her brothers Edward and Thomas - and later migrated into given-name use in the 18th–19th centuries, peaking in early 20th‑century Anglophone records. Seamour remains rare and stylistically modern. Standard variant: Seymour; other spellings include Seymore, Seamore, and Seamor. Nicknames include Sy and Sey; feminine elaborations like Seymoura occur occasionally.
