Gisilbert is an Old German form of Gilbert. The name is composed of the Old German elements gisal meaning "pledge, hostage" and beraht meaning "bright," thus carrying the combined sense of "bright pledge."This Germanic compound name was common among early medieval European nobility and was introduced to England by the Normans. The variant Giselbert is a closely related form. In French and modern English, the name evolved into the popular Gilbert, while in Spanish it became Gilberto. Diminutive English forms include Gib and Gil.The name Gisilbert itself seldom appears in modern records, but its legacy persists through the Latinized form Gilbert. For notable bearers and historical context, the name is closely tied to the stories of the 12th-century English saint Gilbert of Sempringham, founder of the Gilbertine order.Meaning: "Bright pledge"Origin: Old Germanic elements gisal and berahtType: First nameUsage Regions: Germanic, Norman England
