Ghislain

Masculine Ghislain, Guislain, Gislain or Ghiselin and feminine Ghislaine or Ghyslaine is a French personal name used in countries with French-speaking populations. It is originated with a 7th century saint, Saint Ghislain (died 680) of Hainaut and was latinized as Gislenus.

Etymologically, the name is usually said to derive from the oblique case of a Proto-West Germanic root: *gīsl “hostage, pledge” (see Ghislain). As such, it is cognate with modern German Geisel "hostage". (However, one source has instead claimed that the name is derived from Germanic roots gis "information" and lind "sweet". ) The name possibly became popular as a secondary given name, which was intended to give infants the protection of St Ghislain.
