The Three Ladies of Saint-Ours, ca. 1850s
One particularly interesting example was found on the daguerreotype known as The Three Ladies of Saint-Ours, which was produced between 1850 and 1860. The portrait features three sisters from the Saint-Ours family, one of Quebec’s foremost seigneurial families: Caroline-Virginie (1835–1894), Josephte-Hermine (1834–1900) and Henriette-Amélie (1837–1916).
