Marchant is of Norman origin, derived from the Old French word 'marchant', which means 'merchant'. It was originally an occupational name given to a merchant or tradesman. The name is also found as a surname, with notable bearers including Sir William Marchant, an English politician and merchant in the late 14th century. In some cases, Marchant may have been given as a nickname to someone who was thought to be acting like a merchant, perhaps in terms of being shrewd or enterprising.
"In 1972, there were seven individuals named Marchant born annually."
