According to the narrator, what happened one-hundred years ago in the story, The Wives of the Dead?

A hundred years ago, in the early eighteenth century, two "young and comely" (attractive) women in a Massachusetts seaport town married brothers and set up house together. In "two successive" days, they learn of their husbands' deaths: one is lost at sea, while the other is killed fighting the French and Indians in Canada. The British battled with the French for control of North America at this time, and colonists from the Bay colonies often fought on the Canadian frontier. Though many townspeople turn out to offer their sympathy, the women want to be left alone to console each other.
