A moine is a friar or a monk, if that is your question. Most city names (there are exceptions) are never translated

Information about the origin of the name (NOT what I thought AT ALL!!). THANK YOU for asking!!
The history of Des Moines can be traced to 1834, when John Dougherty, an Indian Agent at Fort Leavenworth, Ks, recommended that a military post be established at the point where the Des Moines and Raccoon Rivers merge. Nine years later, May 1843, Captain James Allen and a company of dragoons from Fort Sanford arrived on the site. Captain Allen proposed to name the
garrison Fort Raccoon but was directed by the War Department to use the name Fort Des Moines. The origin of the name is uncertain, but most historians agree that the name probably initially referred to the river. Some people feel that 'Des Moines' is derived from the Indian word 'moingona' meaning
river of the mounds which referred to the burial mounds that were located near the banks of the river. Others are of the opinion that name applies to the Trappist Monks (Moines de la Trappe) who lived in huts at the mouth of the Des Moines river. French voyagers referred to the river as La Riviere
des Moines. The consensus seems to be that Des Moines is a variation of Moingona, Moingonan, Moingoun, Mohingona, or Moningounas, as shown on early maps.

Another opinion:
The True Meaning of Des Moines
Linguistic research has shed new light on the meaning of 'Des Moines.' Turns out it might derive from a 330-year-old practical joke. In 1673 Father Jacques Marquette met some representatives of the Peoria indian tribe near the mouth of the modern-day Des Moines River. He asked them the name of the rival tribe that lived further along the banks of the river. The Peoria told him that tribe was called the Moingoana, which became the root for the word 'Moines'. But researcher Michael McCafferty of Indiana University, while studying the now extinct Miami-Illinois language, discovered that Moingoana, translated literally, meant 's**t faces.' Evidently the Peoria were having a little fun at their rival's expense. The city of Des Moines has not yet acknowledged the true meaning of its name.
