Joseph de La Roche Daillon

Joseph de La Roche Daillon (died 1656, Paris) was a Franciscan Récollet priest and a French missionary to the Wendat (Huron) and Attawandaron (Neutral). He is remembered in Canada as an explorer and missionary, and in the United States for his alleged discovery of the first recorded source of petroleum in North America.

Daillon was the son of Jacques de La Roche, seigneur of Daillon in Anjou, and of Jeanne Froyer of La Baronnière. His career as a missionary in New France in the 1620s lasted less than five years.

Arrival in New France

Daillon arrived at Quebec from Dieppe on June 19, 1625. He had been asked by his superiors to provide assistance to Father Nicolas Viel, a missionary to the Wendat. He had travelled as far as Trois-Rivières in the company of Jesuit missionary Jean de Brébeuf, when he learned of Father Viel's death. On the advice of their Wendat and French escorts, both men decided to turn back.

Missionary to the Attawandaron

In October 1626, Daillon received a letter from his superior, Father Joseph Le Caron, directing him to minister to the Attawandaron, called the Neutral by the French. They were given this name because they did not take sides during the conflicts between the Wendat and Haudenosaunee (Iroquois). The Attawandaron lived south of the Wendat near the head of Lake Ontario, along the Grand River, and in the Niagara Peninsula. In his account of his time among them, Daillon reported that they had 28 villages.

At Ounontisaston, Daillon encouraged the Attawandaron to trade directly with the French, and sought converts to Catholicism. His time among them, however, ended poorly. The Wendat, unhappy with a French presence among the Attawandaron, spread rumours that Daillon was a sorcerer. Daillon records that he was subsequently beaten and his baggage pillaged by some men from Ouaroronon who had come to trade with the Attawandaron. Daillon left Ounontisaston in March 1627 and returned to Toanché. This claim has been uncritically accepted and embellished in later works such as John Herrick's Empire Oil: The Story of Oil in New York State. Herrick asserts that the village where Daillon lived for 3½ months was located near the oil spring, however, it is generally accepted by archaeologists and historians that Souharissen's village was in the Grand River watershed.

Daillon's own account fails to support these claims as the word "oil" appears only once in his writing, in the context of the food produced by the Neutral: "They have squashes, beans, and other vegetables in abundance, and very good oil, which they call Touronton." Gabriel Sagard in his Histoire du Canada recorded how the neighbouring Wendat extracted oil from sunflower seeds which suggests that Daillon's "oil" may have been sunflower oil.

Leaving the Wendat and New France In 1628, Daillon left Toanché and returned to Trois-Rivières with a group of Wendat bringing pelts to trade. From there he journeyed to Quebec, and was ministering there in May 1629. When the French briefly surrendered control of New France to the English in 1629, the Catholic missionaries were forced to leave the province. Daillon was the Latin language interpreter during the capitulation. He left Quebec on September 9, 1629, and died in Paris in 1656.

Legacy

De La Roche Hall, the main science building at St. Bonaventure University in Western New York is named after the missionary. Exterior details on the building have a petroleum theme reflecting his alleged discovery.
