Hi Robert: The Yves Rossignol you mention is in my direct lineage on my mother's side.
He was baptised under the name Henri in 1787, but never used that name. He died young in 1846. During the War of 1812, he was a sergent in the third batalion. Later he was militia captain in his village of St-Denis-de-Kamouraska Qc, later still, he was major till his death. Respected businessman, one of the witnesses at his funeral was Jean-Charles Chapais, one of Canada's "fathers of confederation" in 1867.
His wife was a widow. These were their children:
1. Marie-Théotiste, b 1820, m Clovis Dionne 28-11-1848 at St-Denis-de-Kamouraska; 2. Marie-Pélagie, b 1820 d 1867, m Ovide Michaud ca 1849; 3. Marie-Céleste, b 1822, m Félix Sérien dit Langlais (architect, descended from a child, Daniel Sergent, kidnapped from Worcester MA by the indians in 1704) 1-2-1842 at St-Denis-K; 4.

Thomas-Elie, b 1824, m Marie-Luce Pelletier 11-2-1851 at St-Denis-K; He settled at Hébertville Qc in the Lac St-Jean area.
Hope this answers some of your questions on my ancestor.
