Origin of Eloise

[geeves]

Can anyone help me with the origin of the name Eloise. My baby name books and various websites are giving me many different answers from Louise, to Helen, to Aloysius, etc... Some say it's German, some say French, some say English. Help! :)

Louise and Aloysius would be the same origin, because they are both forms of Louis.

According to behindthename.com , Eloise is a form of Heloise:
