Guisel is an uncommon given name of German origin, derived from the Germanic elements 'wis' meaning 'wise' and 'hel' signifying 'protection'. It is a unisex name but was more commonly used for males in past centuries. The name Guisel was popular during the Middle Ages in Germany and has since fallen out of fashion, making it quite rare today.
"Guisel is quite rare, with only five people born with that name each year between 1997 and present."
