The original Wentworth Township, formed in 1809, included both
Wentworth and Wentworth-Nord, so their histories are closely related until 1958 when Wentworth-Nord became a separate municipality. The community of Laurel formed when the first families arrived from Ireland between 1855 and 1860, calling it New Ireland in memory of their homeland. The Laurel Post Office opened in 1886. In 1856, the mission of Wentworth was established, officially renamed to Saint-Michel in 1884. By 1860, McCluskey or McClosky Court opened, probably named after pioneer James McClosky. From 1899, several mines were commercially exploited, extracting
mica (from 1899 onward),
chalk (from 1919 to 1923),
marl, and
graphite. Other economic activity included logging, agriculture, and the manufacture of
potash. == Geography ==
