Gilbert m. Old High German gīsal 'pledge, hostage' + Old High German beraht, Old Saxon berht 'bright' from Proto-Germanic *berhtaz.

The name of an 11th C French saint, a 12th C English saint, and a 13th C Scottish saint.

The English diminutives Gib, Gyb, and Gybon are witnessed in 1379 in the relational bynames Gibwyf' (WRYPT1 p. 18), Gybsoñ (WRYPT1 p. 18), and Gybonsoñ (WRYPT1 p. 149). The name Gilo was sometimes used as a nickname of Gilbert, as in the 1271 example of Giselbertus dictus Gillo (hennes-vol1, 218).
