Example Input: Question: How old was Jacques Cartier when he named Baie des Chaleurs? Passage:Bathurst had been the location of the annual Mi'kmaq summer coastal community of Nepisiguit prior to European settlement. Europeans first reached the shores of the Baie des Chaleurs when in 1534 it was named by Jacques Cartier. Early settlers from France came to the area in the 17th century in what became part of the colony of Acadia. In 1607 Samuel de Champlain sailed into the Miramichi, and in 1636, Nicolas Denys was granted a seignory by the French crown, apparently the third grant in the colony of Acadie. Jean Jacques Enaud, who hailed from the French Basque Country, was granted in 1638 the seignory at the southeastern gap of the harbor later named Alston Point. Remark is made on William Francis Ganong's map of Bathurst Harbour, depicted here at left, of the residence of Nicolas Denys and the seignory of Gobin.
