Jean-Baptiste Dumouchelle (5 April 1784, in Dumouchel – 29 March 1844) was born in Sandwich (now Windsor), Quebec.
He was a leading figure in Saint-Benoît through his pursuits as a militia officer, general merchant and magistrate.
At the age of 11 Dumouchelle left Sandwich, completing his classical studies at Collège Saint-Raphaël in Montreal in 1803.
After his marriage to Victoire Felix and the birth of their four children, Dumouchelle achieved the rank of captain in the Rivière-du-Chêne battalion of militia serving in the War of 1812.
When he returned to Saint-Benoît he found his home and business in ruins from the pillaging of Colborne's troops during 1837.
