Richer Family History

English (East Anglia) French and German: from a personal name composed of the ancient Germanic elements rīc ‘power(ful)’ + hari heri ‘army’. The name was introduced into England by the Normans in the form Rich(i)er Ricier but was largely absorbed by the much more common Richard.

Altered form of French Héricher: from the ancient Germanic personal name Harigari composed of the elements hari ‘army’ and gari (from garwa) ‘ready eager’ or gari ‘spear’ or a variant of Hérissé, a nickname for someone with spiky hair from the adjective hérissé a derivative of the verb se hérisser ‘to stand on end’.

Probably also an Americanized form of German Ritscher. Compare Ritcher.
