Jean-Pedro Lesieur (1780-1854) came to Canada as a member of the De Meuron Regiment, which fought in the War of 1812. His wife, Marie-Esther Tremblay was the g-g-granddaughter of Genevieve Gagne (1686-1731), while his granddaughter Philomene Bellefleur married Joseph Gagner; therefore, there is a tie-in to the Gagne family at "both ends".
