Seimor is English in Origin.

Seimor is a modern phonetic respelling of the English given name and surname Seymour. Seymour traces to Norman French toponyms Saint-Maur, introduced after the Norman Conquest; Saint-Maur honors St. Maurus (Latin Maurus meaning “a Moor, dark-skinned”). As a surname it became prominent in Tudor England through the Seymour family, notably Jane Seymour, third wife of Henry VIII, and her brother Edward, Duke of Somerset.

As a given name, Seymour rose in Britain and America in the 18th-19th centuries, peaking early 1900s before fading; today it reads vintage. Seimor remains rare, chosen by parents seeking a distinctive twist with the same heritage and sound. Variants include Seymour, Seymor, Seamor; short form Sy/Sey occurs as a nickname. In French the cognate is Saint-Maur, while Mauro shares the Latin root but is not a direct variant. The core meaning is "from Saint-Maur" or "belonging to St. Maur(us)."
