Tacumwah (c. 1720 – c. 1790), alternate spelling "Taucumwah", aka Marie-Louise Pacanne Richerville (Richardville), was a businesswoman and prominent chieftess of the Miami tribe.
Richerville — who later Anglicized his name as Richardville, the form in which he passed the name to his son — later left the area and became a fur trader in Canada.
[3] Richerville physically beat Tacumwah in the ensuing argument, and she took refuge with his business rival Charles Beaubien.
Pacanne and Beaubien physically threatened Richerville and the Maisonville brothers, and the matter was taken to court at Fort Detroit on 18 September 1774.
She reportedly once put a knife into Peshewa's hand and told him to free a white captive whom other tribesmen were about to execute.
