context: Some disagree with such double or triple non-French linguistic origins, arguing that for the word to have spread into common use in France, it must have originated in the French language. The "Hugues hypothesis" argues that the name was derived by association with Hugues Capet, king of France, who reigned long before the Reformation. He was regarded by the Gallicans and Protestants as a noble man who respected people's dignity and lives. Janet Gray and other supporters of the hypothesis suggest that the name huguenote would be roughly equivalent to little Hugos, or those who want Hugo.
