His wife Elisabeth (née Haguin), my 9x maternal great-grandmother, was home recovering from the birth of her seventh child. With her were her five surviving children, Jeanne, François, Marie Madeleine, Jean Baptiste, and Marguerite.  Elisabeth also had four older children, three daughters and one son (Antoine, my ancestor), by her late first husband Antoine Courtemanche dit Jolicoeur.
Within a few months, life changed dramatically for Elisabeth. A trio of illnesses – pleurisy, measles, and malignant fever – soon appeared in the colony.  In July, measles broke out among the day-students at the Ursuline convent in Quebec (city) and spread to the boarding students and the teaching nuns.  It reached epidemic proportions in Lachine, near Montreal, where deaths were recorded from August to late December. 
Rénald Lessard in his Au temps de la petite vérole was aware of the problem of correctly identifying the epidemic. He notes that it was also a concern for the colonial authorities like the Marquis de Denonville (Governor General of New France) and de Champigny (Intendant of New France), who wrote, “Ces maladies ont commencé par la rougeolle Il y a du pourpre et ensuite des fluctions Sur la poitrine”. (These illnesses began with measles, there is typhus and then [presumably dysentery].) 
Author and demographer Hubert Charbonneau wrote an article in the mid-1990s about the “grandes mortalités épidémiques” (great epidemic mortalities) in New France prior to 1760. He identified the 1687 epidemic as typhus. 
Four members of the Daveluy family succumbed to the epidemic in late 1687. In the span of twelve weeks, Elisabeth lost three children and her husband.  First, eldest daughter Jeanne (13) died on 3 October and was buried that day. Then, son François (11) died; he was buried on 9 November. Daughter Marie Madeleine (9) was buried on 25 November. Four weeks later, husband Paul was buried on 21 December. (The burial records of the last three do not indicate a date of death, but it’s likely that they were buried the day they died.) 
Elisabeth and her three youngest children were spared. She never remarried, and died in April 1718, thirty years after the fateful year of 1687.
