Origin of Des MoinesFr, literally , of the monks
From the French name of the nearby Rivière des Moines, which superficially means "river of the monks" and has traditionally been interpreted as a reference to the Trappist monks who settled along it. "It is more likely, however, to be a name of Native American origin, recorded in a 1673 text as moinguena", which recent research has interpreted a Miami mooyiinkweena (“shit-face”), a derogatory designation the Peoria tribe used for their Moingona neighbors.
