Geordan is a unisex given name of Scottish origin, derived from the Scottish Gaelic word 'Gearóidín', which is a diminutive of Gearoid, meaning "little Gerald." This name gained popularity in Scotland and Ireland during the medieval period but has since become quite rare. In English-speaking countries today, Geordan is typically used more often as a surname than a given name.
"The name Geordan peaked in popularity between the late 1980s and mid-1990s with a notable spike in 1993 having 31 births that year."
