Hervey is an uncommon given name of English origin, derived from the Old French word 'Herveu', which means "hereditary". It was traditionally used as a surname before becoming a first name in some families. In medieval France, it denoted someone who held land by hereditary right. The name Hervey is associated with the Norman conquest of England in 1066 and has been used among the English nobility throughout history.
"Hervey's popularity peaked around WWI with a high of 30 births in both 1917 and 1918. Post-war, it declined rapidly, becoming quite rare by the 1960s. Since then, it has remained fairly uncommon, with most years seeing fewer than 10 births."
