Eldest child of Charles Amable and Thérèse (née Poitras) Gagnon, Charles was born on 2 May 1797. He was baptised five days later in the parish church of St-Roch-de-l’Achigan, about 60 km (37 miles) north of Montreal.  Charles had five brothers (Joseph, François, Jean-Baptiste, Pierre, and Toussaint) and one sister (Marie Marguerite Thérèse, who died young).
