The history of the last name Guillory

The surname Guillory is believed to have originated in France, specifically in the regions of Poitou and Saintonge. It is derived from the Old French name "Guillery" or "Guilleri," which is thought to have roots in the Germanic personal name "Wilhari" or "Wilheri."

The earliest recorded instances of the name Guillory can be traced back to the 12th century in various medieval documents and records from the Poitou-Charentes region of western France. One notable early mention is in the Cartulaire de l'Abbaye de Fontaine-le-Comte, a 13th-century manuscript that references a "Petrus de Guilleria" in a land transaction.

Over time, the name evolved to include variations such as "Guillerie," "Guilleri," "Guillory," and "Guilleri." These different spellings were often used interchangeably, reflecting the regional dialects and the inconsistencies in record-keeping during that era.

While the name Guillory does not appear in renowned historical records like the Domesday Book, it has been associated with several notable individuals throughout history.
