The name derives from the Old German word "gisel" (ray, the radiant). It is also the name of a famous 19th-century ballet whose heroine is a peasant girl.
Very smart, honest and optimistic. Not one to beat around the bush. All Gisel's have a bit of a dark side you definitely don't want to get on their bad side. Never question their honesty or loyalty, they find it offensive.
Gisel is lady on the streets but a freak in the bed.
