The Ancient Germanic name Hlutwig was Latinized into Ludovicus. The French shortened this to Clovis, and over time dropped the ''c'' and changed the ''v'' to a ''u.'' Voilá, Louis. In the opinion of the French, this was an excellent name for a king -- eighteen of them, in fact.
Somewhere in this progression, the feminine Latin form Louisa was changed by the French into Louise, and from the interplay of these names a bouquet of girls' names grew -- Eloise, Heloise, Eloisa, Luisa and others.
