Catherine derives from the Greek name Aikaterine, which spawns from the root word:
Catherine is a very regal name, belonging to multiple Queens. It also belonged to the virginal Saint Catherine of Alexandria, who was also a princess and was martyred at the age of 18. Additionally there is Saint Catherine of Siena, who is the Patron Saint of nurses, Italy and the persecuted.
Some other names that stem from Aikaterine include Catarina, Katalini, Caitlin, Katrina, Kalena and Cadi.
