Sorry, my mistake!I was looking at the wrong marriage.Too early in the morning, I guess.:)Here is where I read about "Jean's only daughter, Marie..."
"FIRST DOUBLE MARRIAGE IN CANADA - 1637
....Jean Guyon was employed by Robert Giffard and had married Mathurine Robin in 1616 at Saint Jean de Mortagne.
Jean's only daughter, Marie, born 18 March 1624, was 10 years old at her arrival in New France.
The records indicate that Francois Bellanger was baptized on 7 October 1612, the son of Francois Bellanger and Francoise Horlays in the diocese of Lisieux, County of Touque in Normandy. Marie Guyon, who was also from the County of Touque in Normandy, married Francois on 12 July 1637 in Quebec. Francois and Marie were married 3 years after their arrival, in the chapel of Notre Dame de Recouvrance (which burned in 1640). His union with the thirteen year old Marie Guyon, was blessed by Father Charles Lallemant, acting as the curate of Notre-Dame-des-Anges. "
