Yamachiche

Yamachiche lies on the northern shore of Lake Saint-Pierre, where streams descend into the broad waters of the Saint Lawrence. Its name, applied to the rivers before the village, comes from an Indigenous word associated with muddy water. Algonquin hunters camped along the river, seeking moose in the surrounding country. The forested shore later formed part of the seigneury of Grosbois, granted to Pierre Boucher in the seventeenth century.

Permanent French settlement took root around 1703, and a wooden chapel dedicated to Saint Anne was built in 1711. The parish followed in 1722, and a stone church replaced the first chapel two years later. The Chemin du Roy, opened in 1737, linked Yamachiche with other settlements along the north shore. In 1767 Acadians displaced by the British deportations arrived in the eastern part of Grosbois and made new homes there.
