The essentials is in my preceding message.
Your ancestor, Phylias Joncas, originates from the Gaspé Peninsula.
The first, and only, European Joncas, Pierre, was born Nov. 1644 in Maurens, France. A soldier, he arrived in Québec with the Carignan Regiment, in June 1665 to fight the Iroquois.
He opted to stay in Nouvelle France and married Jacqueline Boulay in Île d'Orléans on June 8, 1672. Jacqueline was 13 yoa. She was born April 10, 1659 in St-Germain de Loisé, Perche, France. She could read and write.
They later moved to Montmagny, on the south shore of the St Lawrence river.
From there, around 1800, your ancestors moved to Grande-Rivière, on the Gaspé Peninsula.
Francis-Carter Joncas, married to Christina McInnis, is of the 10th generation of Joncas in America.
