The history of the last name Isidore

The surname Isidore has its origins in the Late Latin name Isidorus, itself derived from the Greek name Isidoros, meaning "gift of Isis" - Isis being an ancient Egyptian goddess. The name first emerged in medieval France and Spain in the Early Middle Ages.

The surname likely originated from the veneration of Saint Isidore of Seville (c. 560-636), a scholar and Archbishop of Seville who was influential in preserving and promoting learning during the Early Middle Ages. His writings covered a vast array of topics and were widely read and copied throughout medieval Europe.

One of the earliest recorded bearers of the surname was Isidore de Seville, a Benedictine monk who lived in the late 11th century. He is mentioned in a manuscript from the Abbey of Saint-Martial in Limoges, France, dated around 1090.

In England, the surname can be traced back to the 13th century, with one William Isidore appearing in the Hundred Rolls of Oxfordshire in 1273. The name was also present in medieval records from other parts of Europe, such as the Low Countries and Italy.

A notable bearer of the name was Isidore of Kiev (c. 1385-1463), a monk and missionary who helped introduce Orthodox Christianity to areas of modern-day Russia and Belarus. Another was Isidore the Farmer (c. 1070-1130), a Spanish day laborer who was later canonized as the patron saint of farmers.

Other prominent individuals with the surname include Juan Isidro Fajardo (1537-1629), a Spanish writer and historian, and Isidore Geoffroy Saint-Hilaire (1805-1861), a French naturalist and zoologist. Antoine Isidore Hippolyte Mellinet (1801-1867) was a French novelist and playwright.

The name has also been associated with various place names, such as Isidore, Texas, and Saint-Isidore, a municipality in Quebec, Canada. These likely derive from the veneration of Saint Isidore or have connections to early settlers bearing the surname.
