Roger is primarily a proper name of English, French and Catalan usage, derived from the German name Rüdiger which means "famous with the spear" from the Germanic elements hrod (fame) and ger (spear). The Latin form of the name is Rogerius, as used by a few medieval figures.
The name "Roger" was transmitted to England by the Normans after the Norman Conquest along with other names such as William, Robert, Richard, and Hugh. It replaced its Anglo-Saxon cognate, Hroðgar.
